Create a function named exponents() that takes two lists as parameters named bases and powers. Return a new list containing every number in bases raised to every number in powers.

For example, consider the following code.

exponents([2, 3, 4], [1, 2, 3])

the result would be the list [2, 4, 8, 3, 9, 27, 4, 16, 64]. It would first add two to the first. Then two to the second. Then two to the third, and so on.
