Which expression is equivalent to (7^8)^7? Choices: (A)1/7^15 (B)1/7^56 (C)7^56 (D)7^15

Apply power rule: Apply the power of a power rule. The power of a power rule states that (a^m)^n = a^(m*n). So, (7^8)^7 = 7^(8*7).Calculate new exponent: Calculate the exponent. Multiply the exponents 8 and 7 to find the new exponent. 7^(8*7) = 7^56.Match with choices: Match the result with the given choices. The calculation from Step 2 gives us 7^56, which matches choice (C).
