Tolong bantu yang di ceklis...saya udh mentok banget..Sebelumnya makasih

1. c
4^3 = 64
^4 log 64 = 3

2. b
^0,5 log 0,0625 = 4
^0,5 log (1/16) = ^0,5 log 0,5^4
1/16 = 0,5^4
1/16 = 1/16
2^-4 = 2^-4

3. e
^4 log 4^10
= 10 . ^4 log 4
= 10 . 1
= 10

4.a
log 18
= log (3² × 2)
=log 3² + log 2
= 2 . log 3 + log 2
= 2 . 0,4771 +0,3010
= 1,2552

4. b
log 21
= log (7 × 3)
= log 7 + log 3
= 0,8451 + 0,4771
= 1,3222

2][
0,5'log 0,0625 = 4
0,0625 = (0,5)^4

3][
4'log 4^10
= 10 . 4'log 4
= 10

4][
log 18
= log (3² × 2)
= log 3² + log 2
= 2 × 0,4771 + 0,301
= 1,2552

log 21
= log (3 × 7)
= log 3 + log 7
= 0,4771 + 0,8451
= 1,3222
