Okay, so what is 4 * 4?

Because the exponent is 2, you multiply the number UNDERNEATH the exponent by itself. It the exponent is three, multiply the number by three. So it would be number * number * number.

OpenStudy (anonymous):

No, remember you multiply the 7 * 7 because of the 2. So you multiply the number by itslef. Then for the three, you multiply the three by itself 3 times. So 7*7 + 2*2*2 is 49 + 8 which equals.......
