pply the Property of Negative Integer Exponents to rewrite 7^-3.7^-5
as an expression with positive exponents only.
To apply the property of negative integer exponents, we can rewrite 7^-3 as 1/7^3 and 7^-5 as 1/7^5.
Therefore, 7^-3.7^-5 can be rewritten as (1/7^3) * (1/7^5).
To simplify further, we can combine the fractions by multiplying the numerators and multiplying the denominators.
(1/7^3) * (1/7^5) = 1/(7^3 * 7^5)
Using the property of exponents, we know that when we multiply two numbers with the same base, we add the exponents.
So, 7^3 * 7^5 = 7^(3+5) = 7^8
Therefore, 7^-3.7^-5 can be rewritten as 1/7^8, where the exponent is positive.
