Question

(05.02 MC)
Solve 2 log x = log 64.
Ox= 1.8
Ox=8
Ox= 32
Ox = 128

Answer 1

x = 8

Explanation:

`2logx=log64\\logx^2=log64`

now that both sides has log, you can remove them and leave it as:

`x^(2) =64\\`

take the square root of both sides:

`x = [8, -8]\\x = 8`

logarithmic equations can't have negative solutions, plus -8 isn't an option

i hope this helped!
