To simplify the expression 15^0 x 7^-2/(-4)^-3 and convert all exponents to positive, you can use the Properties of Integer Exponents. Recall that any number raised to the power of 0 is equal to 1.

First, apply the property that any number raised to the power of 0 is 1. So, 15^0 becomes 1.

Next, apply the property of negative exponents. Any number raised to a negative exponent can be rewritten by taking the reciprocal of the base and changing the sign of the exponent. Therefore, 7^-2 becomes 1/7^2, and (-4)^-3 becomes 1/(-4)^3.

Now, the expression becomes: 1 x 1/7^2 / 1/(-4)^3.

To simplify further, multiply by the reciprocal of the denominator: 1 x 1/7^2 x (-4)^3.

So, the equivalent expression with only positive exponents generated by applying the Properties of Integer Exponents is:

d. (-4)^3/7^2.
