log √3 3^4 = logx 4
4 log √3 3 = log x 4
4 log √3 (√3)^2 = log x 4
(2 * 4 ) log √3 (√3) = log x 4 ( log √3 (√3) = 1)
2 * 4 * 1 = log x 4
8 = log x 4 (x must be positive)
This means that x^8 = 4 → take the positive 8th root of both sides....
x = 4^(1/8) = (2^2)^(1/8) = 2^(1/4)
So
log 2 x = log 2 2 ^(1/4) = (1/4) log 2 2 = (1/4) * 1 = 1/4
And you are correct !!!!!
Start with the LEFT side
Using the definition of logs : ( 31/2 )n = 34 shows n = 8 ( or you can just use a calculator to find the L side = 8)
so the left side = 8
8 = logx 4
since y = log2 x then 2y = x ( using definition of logs)
then 8 = log 2y 4
( 2y )8 = 4 (using definition of logs again)
28y = 22 (equate the exponents)
8y = 2
y = 1/4
