To simplify the expression (6^2)^4, we can use the Power Rule of Exponents. The rule states that when we raise a power to a power, we multiply the exponents.
In this case, the base is 6, and the first exponent is 2. So, we raise 6 to the power of 2:
6^2 = 36
Now, we take this result and raise it to the power of 4. This means we need to multiply the exponent 2 by 4:
36^4 = 36^(2 * 4) = 36^8
Therefore, the simplified expression is 36^8.
