Which is equal to 3^3/3^-1?

A -81
B -1/81

You're welcome, Jillian.

To simplify the expression 3^3/3^-1, you need to apply the exponent rules.

First, let's simplify the numerator, which is 3^3.
3^3 means 3 raised to the power of 3, which can be calculated as 3 * 3 * 3 = 27.

Now let's simplify the denominator, which is 3^-1.
3^-1 means 1 divided by 3 raised to the power of 1. Since any number raised to the power of -1 is the reciprocal of that number, 3^-1 is equal to 1/3.

Now combining the numerator and denominator, we get:
27 / (1/3)

To divide fractions, we multiply the numerator by the reciprocal of the denominator:
27 * (3/1)

Simplifying further:
27 * 3 = 81

Therefore, the answer is 81, which corresponds to option D.
