Step-by-step explanation:
Let's look at #1 as an example.
The question asks us to find the product of 
One way to look at this product is however many 2's being multiplied together. That would look as so

This would simplify to

As there are 9 2's being multiplied together, we can write this as

This, however is the long and hard way to do each of these problems.
We began with
and ended with 
As we can see, our answer was just the sum of the exponents.
Now that we know that when you multiply two exponents with the same bases, all you have to do is add the powers, you should be able to do the rest of the problems.
