Question

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 know that any number raised to the power of -n is equal to 1 divided by that number raised to the power of n.

So, applying this property to 7^-3:

7^-3 = 1 / 7^3

To simplify further, we need to evaluate 7^3:

7^3 = 7 × 7 × 7 = 343

So,

7^-3 = 1 / 343

Therefore, the answer is 1/343.
