Answer:
9.0
Step-by-step explanation:
[tex]\sqrt{9\times9}[/tex]
Calculate
[tex](9\times9)^\frac{1}{2}[/tex]
Calculate the product or quotient
[tex]{81}^\frac{1}{2}[/tex]
Simplify using [tex]a^\frac{m}{n}=\sqrt[m]{a^n}[/tex]
[tex]\sqrt{81}[/tex]
Factor and rewrite the radicand in exponential form
[tex]\sqrt{9^2}[/tex]
Simplify the radical expression
[tex]9[/tex]
Round 9 to the required place
