Here's a quicker way to check your answer. Go to Wolfram Alpha and type in your problem. It will simplify it for you and you can see if your answer matches.1.) 16 3/2

=16 1/2

=(2 square root)^3

=(2(4x4)^3

=(2 square root 4)^3

You need to be careful though when entering the problem. For example, your problem should be written there as 16^[3/2]. The ^ symbol means exponent. If there's a fraction, put the fraction inside [] brackets.
