Answer 2

To simplify the expression (a^7)^2 / a^12 when a = 5, we can use the laws of exponents.

First, let's simplify the numerator: (a^7)^2 = a^(7 * 2) = a^14

Now, let's simplify the denominator: a^12

Finally, we can substitute a = 5 into both expressions: Numerator: (5^7)^2 = 5^14 Denominator: 5^12

Therefore, the simplified expression (a^7)^2 / a^12 when a = 5 is: (5^7)^2 / 5^12 = 5^14 / 5^12

To simplify the division, we subtract the exponents: 5^14 / 5^12 = 5^(14 - 12) = 5^2 = 25

Therefore, (a^7)^2 / a^12 when a = 5 is equal to 25.
