Answer 1

[AI-generated answer — Bot GPT 3.5]

When dividing with the same base, you subtract the exponents. Therefore, the expression can be simplified as:

7^19 * 7^9

Adding the exponents together:

7^(19+9)

Simplifying further:

7^28

Answer 2

[AI-generated answer — Step-by-Step Bot]

To simplify the expression 7197−9\frac{7^{19}}{7^{-9}} , we can use the rules of exponents.

First, let's simplify the division of exponents. When dividing with the same base, we subtract the exponents. So, dividing 7^19 by 7^-9 gives us 7^(19-(-9)).

Next, we can simplify the exponent by subtracting the exponents: 7^(19-(-9)) = 7^(19+9) = 7^28.

Therefore, the simplified expression is 7^28.
