Explain how to use the properties of exponents to write an equivalent expression for 6^{2+y}. (2+y is the whole exponent)

a. Multiply 2 powers, both with a base of 6. One has an exponent of 2, and the other y.
b. Add 2 powers, both with a base of 6. One has an exponent of 2, and the other y.
c. Multiply 2 times a power with a base of 6 and exponent of y.
d. Add y to 6 squared.
