simplify log2 x = -1

I need help simplifying log2 x = -1

I guess you mean solving:

$log_2\ x = -1$

?

Then, you need to know that if:

$log_a\ b = c$

then;

$b = a^c$

Can you try it now? Post your answer! :)

The long way round is:
$log_a\ b = c$

$\frac{log\ b}{log\ a} = c$

$log\ b = c log\ a$

$log\ b = log\ a^c$

$b = a^c$
