Answer 3

Calculation Explanation:

To solve the expression (7^4)^5, we need to follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

In this case, we have an exponentiation operation, so we need to calculate the exponent first.

Let's break down the calculation step by step:

1. Calculate the exponent (7^4): - 7^4 means 7 raised to the power of 4. - This can be calculated as 7 * 7 * 7 * 7 = 2401.

2. Calculate the exponent (7^4)^5: - Now, we need to raise the result from step 1 (2401) to the power of 5. - This can be calculated as 2401 * 2401 * 2401 * 2401 * 2401 = 7,625,597,484,401.

Answer:

The correct answer to the expression (7^4)^5 is 7,625,597,484,401.

Please note that the answer you obtained from the calculator, which is 49, is incorrect. It seems like there might have been a mistake in the calculation.
