——— +
3 7
2. 3x + 2 = 2x
x = -2
3. 1/3 +4/3 = 5/3
4. sifat eksponen kurangkan saja pangkat nya jika bentuk A sama
a¹²³ ÷a¹²²÷a¹ = 123-122-1 = 0
a⁰ =1
5. 134. ¹ ¹
3
------------- x
4 0 2
6. gradien = 4
7. tinggal saling coret 0 dan saling coret 7
maka tinggal 10.
8. 10.000kg . 1ton = 1000kg
9. 56÷56x2 = 2
10 3cm = .. mm
karena turun 1 tingkat maka X10
30mm.
