Jawaban:

1. 8³×4⁵/16²

= 8×8×8×16×16×4/16×16

coret 16

maka 8×8×8×4=(2³)³×2²

=2¹¹ C

2.a³+6.b^-2+-9=a⁹b^-11 E

3. a=64 maka (4+1/4)/8-1/8

17/4/63/8

=34/63 yg mendekati A

4. c karna irasional

5. 4√3-2√3+3√3=5√3 A

6. 14/3-√2 × (3+√2)/3+√2

14(3+√2)/7

= 6+2√2 C

7. ⁵ log 3×4/2(6)= ⁵log 1

maka 1 B

8. log p=a log q=b

maka loga³+log b²= 3 log a + 2 log b

= 3p+2q B

9. log 72= log 2+log 2+log 2+log 3 + log 3

= 3 ( log 2)= 3(0,301)

= 0,903

2(log 3)= 2(0,477)=0,954

maka 0,903+0,954= 1,857 D

10. x²-4x-5=0

(x-5)(x+1)=0

x=5 V x=-1

maka C
