Question

1. $sqrt{\frac{9}{16}} = pm \boxed{\quad} \\\\$4. $sqrt3{27} = \boxed{\quad}$

Explanation:

Step1: Simplify square root of fraction

$\sqrt{\frac{9}{16}} = \frac{\sqrt{9}}{\sqrt{16}} = \frac{3}{4}$

Step2: Identify square root solutions

The square root has two solutions: $\pm\frac{3}{4}$

Step3: Simplify cube root of 27

$\sqrt[3]{27} = 3$, since $3^3=27$

Answer:

1. $\boldsymbol{\frac{3}{4}}$ (top box), $\boldsymbol{\frac{3}{4}}$ (bottom box)
