Using the property of integer exponents that any number raised to the power of zero is equal to 1, we can simplify the expression as follows:
4^0 ⋅ 5^−2/ (−2) ^−3
= 1 ⋅ 5^−2/ (−2) ^−3
Now, using the property of negative exponents that states that any number raised to a negative exponent is equal to 1 divided by that number raised to the positive exponent, we can rewrite the expression as:
= 1 ⋅ 1/5^2/1/ (1/(-2))^3
Simplifying further using the property of negative exponents:
= 1 ⋅ 1/5^2/1/(-2)^3
= 1 ⋅ 1/25/(-8)
= 1/25/(-8)
= 1/25 * (-8)
= -8/25
So, the simplified fraction with no remaining exponents is -8/25.
