If (N=2^4 \times 3^2), what is (\sqrt{N}) equal to?
Answer and explanation
Correct answer: (2^2 \times 3)
Step 1: When taking a square root, halve the prime exponents. Step 2: (2^4) becomes (2^2) and (3^2) becomes (3), so (\sqrt{N}=2^2 \times 3). Step 3: In square roots, halve exponents, not bases.
