Solve log2(x) = 4.5, accurate to two decimal places.

When you are given a log function in the form of
log a (x) = b

this is the same as saying that a^b = x
(a to the power of b is equal to x)

So in your question, 2^4.5 = x
Try entering this into your calculator and see if you get the right answer :)
