Apply the Property of Negative Integer Exponents to solve 6-4. The answer should not contain any exponent expression or decimals.

To apply the Property of Negative Integer Exponents, we will transfer the base from numerator to denominator or vice versa, and change the sign of the exponent.

So, applying the property to 6-4, we get:

6-4 = 1/6^4 = 1/1296

Therefore, the answer is 1/1296.

To apply the property of negative integer exponents, we can rewrite the expression 6^-4 as the reciprocal of 6^4.

Reciprocal of 6^4 = 1 / 6^4

To evaluate 6^4, we have:

6^4 = 6 * 6 * 6 * 6 = 1296

Now, we can substitute this value back into the expression:

1 / 6^4 = 1 / 1296

Therefore, the solution to 6^-4 without any exponent expression or decimals is 1/1296.
