Answer 5

Exponentiation is when you multiply a number by itself a certain number of times. The exponent, the number that comes after the asterisks(**), is the one less than the amount of times you multiply the number by itself. For example, 4**2 is equal to 16 because you are multiplying 4 by itself. 4**2 is the same thing as 4×4, which is equal to 16.
Another example: 2**4 is equal to 16 because the number 2 is being multiplied by itself 3 times, which is one less than the exponent, 4. 2**4 is the same thing as 2×2×2×2 which is equal to 16.
Notice that in both examples the number of 2s and 4s that are being multiplied to each other is equal to the exponent. This is the case for all exponentiation.
