Solve the logarithmic equation: log2 4+log2 x=6
I got x=2, is this correct?
log2 4 + log2 x = 6

log2 4x = 6

4x = 26

4x = 64

, or 

OR

log2 4 + log2 x = 6

log2 22 + log2 x = 6

2 + log2 x = 6

log2 x = 6 - 2

log2 x = 4

x = 24



You can do the check!! 

You should be able to determine if you're correct, or incorrect, I'm sure!!
