Question

radical expressions
16^(1/2)
simplify
?

Explanation:

Step1: Recall exponent rule

The rule for a number raised to a fractional exponent \(a^{\frac{m}{n}}=\sqrt[n]{a^m}\). For \(16^{\frac{1}{2}}\), \(m = 1\), \(n=2\), so it's \(\sqrt{16^1}=\sqrt{16}\).

Step2: Calculate square root

The square root of 16 is 4, since \(4\times4 = 16\).

Answer:

4
