log2(x-5)=5
Homework Equations
I am not sure what this is asking for. There are no other equations.
The Attempt at a Solution
25=X-5
25+5=X-5+5
32+5=X
X=37
Looks good to me. What's the question?
You should be able to take log2(32) in your head. Since 32=2^5. But for future reference, log2(x)=log10(x)/log10(2).
Put x=37. log2(x-5)=log2(37-5)=log2(32)=log10(32)/log10(2)=1.50515/0.30103=5. But again, this isn't a question where you need to rely on a calculator.
