Question

Solve 2 log x = log 64.

Answer 1

hint :
2 log x = log x^2

Answer 2

now you have :
log x^2 = log 64

Answer 3

next, if given log a = log b then a = b.

log x^2 = log 64, then
x^2 = 64
solve for x

Answer 4

just take the squareroot of 64. so
x = sqrt(64) = ..... ?

(in this case, x can not be negative. it must be positive)
