^ = pangkat

nomor 1
1] ²log 8
= ²log 2^3
= 3

2] ^3log 27
= ^3log 3^3
= 3

3] ^7log 49
= ^7log 7²
= 2

4] ²log 2 + ^6log 36 + ²log 16
= 1 + 2 - 4
= -1

nomor 2
1] ^3log 9 = x
3^x = 9
3^x = 3^2
x = 2

2] ^4log x = 2
4^2 = x
x = 16

3] ²log (x + 2) = 3
x + 2 = 2^3
x = 8 - 2
x = 6

4] ^(1/2)log (1/8) = x
(1/2)^x = 1/8
(1/2)^x = (1/2)^3
x = 3
