"""
This function takes two numbers as parameters, the first
number being the coefficient, and the second number being
the exponent.

Your function should multiply the two numbers, and then
subtract 1 from the exponent. Then, it has to print out
an expression (like 28x^7). "^1" should not be truncated
when exponent = 2.

For example:

derive(7, 8)
In this case, the function should multiply 7 and 8, and then
subtract 1 from 8. It should output "56x^7", the first number
56 being the product of the two numbers, and the second number
being the exponent minus 1.

derive(7, 8) --> this should output "56x^7" 
derive(5, 9) --> this should output "45x^8" 
Notes:

The output of this function should be a string
The exponent will never be 1, and neither
number will ever be 0
