Operasi Hitung Bentuk Aljabar

  •     Pemangkatan Bentuk Aljabar
Pemangkatan merupakan perkalian berulang dengan bilangan yang sama.
Contoh :
(3a)² = 9a²
Pemangkatan suku dua : (a + b)² = a² + 2ab + b²
Pecahan Bentuk Aljabar
Pada pecahan bentuk aljabar, penjumlahan dan pengurangan dapat dilakukan dengan menjumlahkan atau mengurangkan pembilangnya sehingga jika penyebutnya berbeda disamakan dahulu.
4/a – 2/b = 4b/ab – 2a/ab = (4b-2a)/ab
a/b  x   c/d = ac/bd
a/b : c/d = a/b  x  d/c = ad/bc
(a/b)ⁿ= a/b  x  a/b  x…..x  a/b  ,sebanyak n faktor
3. KPK dan FPB
  •     KPK ( Kelipatan Persekutuan Terkecil)
KPK merupakan hasil kali factor prima berbeda dengan mengambil pangkat tertinggi untuk factor prima yang sama.
Contoh :
KPK dari 3ab dengan 4a²c adalah :
Factor prima 3ab = 3,a,b
Faktor prima 4a²c = 4,a²,c
KPK dari 3ab dengan 4a²c adalah 3x4xa²xbxc = 12a²bc
  •     Faktor Persekutuan Terbesar
FPB merupakan perkalian factor prima yang sama dengan mengambil pangkat terendahnya.
Contoh :
FPB dari 8ab dengan 4ad adalah :
8ab = 2³ x a x b
4ad = 2² x a x d
FPB dari 8ab dengan 4ad adalah 2² x a = 4a

Studying Abroad


Studying Abroad

I think everyone has his own convinced opinion about studying abroad than inside his country and nevertheless studying abroad has many advantages too. First of all, there are specific specializations that are not offered in your country and studying abroad for this reason will not just add a benefit for you but also for your country. Secondly, by studying abroad you’ll meet different people that have diverse culture than yours and so you’ll not just studying your subject there but also discovering and learning cultures and comparing with your own culture and you might talked to people there about your country too. Also, if you travel alone abroad, this will make you stronger; because you’ll face many challenges and difficulties that force you to act effectively and patiently and manifest yourself among people who don’t know.

My Adolescence

I had my adolescence when I was thirteen.

It started with acne that showed up on my face. It was very annoying. It lowered my self-esteem and I was embarrassed to come out of my house and play with friends.
Fortunately, my Mum gave me a good medicine. In three weeks, the acnes started to vanish although those showed some black spots in my face.

That was my bad experience with adolescence, though there were still lots of good experience too.

Analisa :

Orientation : Paragraf pertama, (I had my adolescence when I was thirteen)
Events : Paragraf kedua dan ketiga.
Reorientation : Paragraf keempat (terakhir)

My Holiday in Bali

When I was 2nd grade of senior high school, my friends and I went to Bali. We were there for three days. I had many impressive experiences during the vacation.

First day, we visited Sanur Beach in the morning. We saw the beautiful sunrise together. It was a great scenery. Then, we checked in to the hotel. After prepared our selves, we went to Tanah Lot. We met so many other tourists there. They were not only domestic but also foreign tourists.

Second day, we enjoyed the day on Tanjung Benoa beach. We played so many water sports such as banana boat, jetsky, speedboat etc. We also went to Penyu island to see many unique animals. They were turtles, snakes, and sea birds. We were very happy. In the afternoon, we went to Kuta Beach to see the amazing sunset and enjoyed the beautiful wave.

The last day, we spent our time in Sangeh. We could enjoy the green and shady forest. There were so many monkies. They were so tame but sometimes they could be naughty. We could make a close interaction with them. After that, we went to Sukowati market for shopping. That was my lovely time. I bought some Bali T-Shirt and souvenirs.

In the evening, we had to check out from the hotel. We went back home bringing so many amazing memories of Bali.

My First Experience to Ride Motorcycle
ditulis oleh Resdwitarini

One day, when I was ten years old, my father bought an old motorcycle. That was " Honda 75". I think it was small light object and easy to ride it. I persuaded my father to teach me to ride " Honda 75 ". Firstly, my father refused my request and promised that he would teach me two or three years later, but I still whimpered. Finally, my father surrendered and promised to teach me.

He began to teach me riding the motorcycle around a field in my village. My father was very patient to give me some directions. I was very happy when I realized my ability to ride a motorcycle. " Yes, I can ".

One day later, when I was alone at home, I intended to try my riding ability. So, myself tried bravely. All ran fluently in the beginning, but when I was going back to my home and I must passed through a narrow slippery street, I got nervous. I lost my control and I fell to the ditch.

After that, I told my father about the last accident. I imagined my father would be angry and never let me ride again. But the reality is exactly on the contrary, my father was very proud of me. He just gave me some advices and since that accident, I got my father's permission to ride motorcycle.

A Page from A Girl's Diary

Tuesday, September 30th, 2008
 
It was takbiran night. It was also my birthday, and nothing happened. Or I had thought nothing would happen, but I was wrong.
 
That night, I was watching television with my family when I heard someone lit fireworks in my front yard. I peeped trough my window glass but could see nothing. It was very dark outside. Then I thought it had to be my cousins who lit the fireworks. Then I plopped down on my sofa again and tried to concentrate on the television since my mind raced with disappointment that no one gave something special on my birthday. I shrugged, it was almost the end of the day and I became pessimist. Five minutes later my mobile beeped. It was a text from my friend asking me to come out. Wondering what was going on, I grabbed my jacket and hurried to the front door. I was surprised to see her bring a bag full of firework and fire drills. Next I was surprised to see my other friend come out from the darkness. She brought a beautiful birthday cake on her hands. Oh my God! I shrieked. Then they gave the cake to me who was too stunned to say anything. I realized I was blushing furiously because my whole family was watching. Not to mention my neighbors too!
