Use the Power Rule of Exponents to create an expression equivalent to (15 ^ 6) ^ 2

a)15 ^ 8
b)15 ^ 4
c)15 ^ 3
d)15 ^ 12

d) (15 ^ 6) * (15 ^ 6) = 15 ^ 12

To simplify the expression (15^6)^2 using the Power Rule of Exponents, we need to multiply the exponents. The Power Rule states that (a^m)^n = a^(m*n).

In this case, the base is 15 and the exponent is 6, so (15^6)^2 becomes 15^(6*2) = 15^12.

Therefore, the correct option is d) 15^12.
