3 log(x) + 5 = 8

Subtract sides 5


3 log(x) + 5 - 5 = 8 - 5


3 log(x) = 3

Divide sides by 3


(3 log(x) )/(3) = (3)/( 3) \\


log(x) = 1

_________________________________

Reminder :


log_(a)(x) = b


x = {a}^(b)

_________________________________

Thus ;


log_(10)(x) = 1


x = {10}^(1)


x = 10

Done...
