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 any number raised to the power of -1 is equal to its reciprocal. Therefore, 7^-3 can be written as 1/7^3.

Now, let's simplify 7^3.

7^3 = 7 * 7 * 7 = 343

So, 7^-3 = 1/343

Therefore, the answer is 1/343.
