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

15^4

15^3

15^8

15^12

15^12

To apply the Power Rule of Exponents, you need to multiply the exponents. In this case, you have (15^6)^2, so you multiply the exponents 6 and 2 to get 6 * 2 = 12. Therefore, an expression equivalent to (15^6)^2 is 15^12.
