Question

What is the solution to the equation log[2] 4 - log[2] x = 3 ?

Answer 1

write it as one log_2 :
log_2 (4/x) = 3

now write this in exponential form:
2^3 = 4/x

can you solve from here?

Answer 2

hmm is it 32?

Answer 3

no...
cross multiply to get a new equation:
x = 4/(2^3)

Answer 4

no x=1/2
