Question

Jika 125^m=64, maka nilai dari 2 log 25^m adalah

Answer 1

125^m = 64
5^3m = 64
5^m = 4

25^m = 5^2m = 16

2 log 16 = 4

Answer 2

125^m=64, ^2 log 25^m?
(5^3)^m = 2^6
(5^m)^3 = (2^2)^3
5^m = 2^2
5^m = 4

^2 log25^m
= ^2 log(5^2)^m
= ^2 log(5^m)^2
= ^2 log(2^2)^2
= ^2 log2^4
= 4

Semoga membantu :)
