Question

Simplify

log2 1/2

Answer 1

Do anyone know how to do this?

Answer 2

What I'd recommend would be that you re-write that 1/2 as a power of 2: 1/2 = 2^(-1).

Answer 3

solve \[2^x=\frac{1}{2}\] for \(x\)

Answer 4

Copy the original problem and substitute 2^(-1) for that 1/2. Does this make the problem solution any more obvious for you? Satellite's approach is perfectly good also.

Answer 5

\[\log_b(x)=y\iff b^y=x\] you should be able to switch back and forth quickly,
that is how you do most of these
