What is the value of \((5^2)^3\)?

Answer and explanation

Correct answer: 15625

Use the power-of-a-power rule: \((a^m)^n = a^{mn}\). So \((5^2)^3 = 5^{2\times3} = 5^6\). Calculate \(5^6 = 15625\), hence option C is correct. Closest distractor 3125 equals \(5^5\) (one exponent short); 625 is \(5^4\) and 25 is \(5^2\), so they are incorrect. Exam tip: always simplify exponents using laws first, then evaluate the base power to avoid arithmetic mistakes.
