simplify this radical expression. assume variables are positive.

Explanation:

Step1: Recall the property of radicals

For a non - negative real number \(x\), \(\sqrt{x^{2}}=x\) when \(x\geq0\). Here we are given that the variable \(a\) is positive.

Step2: Apply the property to \(\sqrt{a^{2}}\)

Since \(a\) is positive, using the property \(\sqrt{x^{2}} = x\) (where \(x = a\) and \(a\geq0\)), we get \(\sqrt{a^{2}}=a\).

Answer:

\(a\)
