Answer 1

20. (1/2)^2 + (1/4)^2 = 1/4 + 1/16 = 4/16 + 1/16 = 5/16 (b)

1. 24 : 12 = 2
2 + 26 = 28
2. 8 - (-4) + 30 : 5
8 - (-4) + 6
8 + 4 + 6 = 18
3. 12/18 keduanya dibagi 6 = 2/3
4. 4/25 = 8/100 = 0,08
5. 2x + 6 = 10
2x = 10 - 6
2x = 4
× = 4 ÷ 2
x = 2
6. 5^2 + 4^3
(5×5) + (4×4×4)
25 + 64 = 89
7. akar 100 = 10
akar pangkat 3 dari 125 = 5
akar 196 = 14
10 ÷ 5 + 14
2 + 14 = 16
8. sisi × sisi × sisi = 1728
akar pangkat 3 dari 1728
= 41,56
9. 32/9
10. 57/100 = 57%
