I think that you have already been given the answers to many of these.

So it is time for you to start learning how to do them.

I will give you some examples that will help.

$$5^{1/2}=\sqrt5\\ 7^{-3}=\frac{1}{7^{+3}}\\ \\~\\ 8^{3/2}=(8^3)^{1/2}=(8^{1/2})^3$$

Now think about it and you tell me what  these are equal to.

$$1) \;\; 2^{-1/2}\\ 2) \;\; 2^{-3/2}\\ and \\ 3) \;\;b^{1/2}$$
