# Simplify the expression: Write the answer using rational exponents, a sqrt[n]{m}, would look like a(m^{(^1/_n)}): 4 sqrt{18} - sqrt{50}

Simplify the expression:
Write the answer using rational exponents,
$a\sqrt{n}\left\{m\right\}$, would look like $a\left({m}^{\left({}^{1}\mathrm{\angle }n\right)}\right)$:
