here is a good summary of the log rules you should know

your equation:
log<sub>2</sub> 4 = log<sub>8</sub> 8 + .5log<sub>4</sub> 16
Left Side = 2
Right Side = 1 + 2 = 3
So, NOT true

Forgot about the .5
"Right Side = 1 + 2 = 3
So, NOT true "
should say:
Right Side = 1 + 1 = 2
So, TRUE
"Right Side = 1 + 2 = 3
So, NOT true "
should say:
Right Side = 1 + 1 = 2
So, TRUE
