apply the property of negative integer exponents to solve 7^-3 the answer should not contain any exponent expression or decimals

Answer 1

To apply the property of negative integer exponents, we can rewrite 7^-3 as the reciprocal of 7^3.

Recall that a reciprocal of a number is just flipping it upside down. So, the reciprocal of 7^3 is 1/(7^3).

Now, using the property of exponents, we know that 7^3 is equal to 7 * 7 * 7.

Therefore, 1/(7^3) is equal to 1/(7 * 7 * 7).

Simplifying this further, we get the final answer: 1/343.
