one way to do this is first change 16 to 2 to some power. can you do that?
the first thing to do here is change 16 to 2 to some power how many times do you multiply 2 times itself to get 16?
4?
2*2*2*2= (2*2) * (2*2) = 4*4= 16 yes 2^4 =16 use this fact in your problem

im confused
16=2^(x-1) replace 16 with 2^4 2^4 = 2^(x-1)
ok now what
If it is not clear, 2^4= 2^(x-1) that means 4= x-1
4=x-1 +1 +1 x=5?
