9 exponent 10<br> Divide by 9 exponent 11

Natasha_Volkova [10]

Answer:

$\frac{\sqrt{110} }{11}$ or $\frac{\sqrt{10} }{\sqrt{11} }$

Step-by-step explanation:

I assume you mean $\frac{9\sqrt{10} }{9\sqrt{11} }$

there is a common factor of 9 in the numerator and denominator so we can cancel out to form $\frac{\sqrt{10} }{\sqrt{11} }$

$\frac{\sqrt{10} }{\sqrt{11} }$ is technically a correct answer, but I will go ahead to rationalize the denominator

multiply $\frac{\sqrt{10} }{\sqrt{11} }$ by some form of 1. this case, we will use $\frac{\sqrt{11} }{\sqrt{11} }$ as our 1.

$\frac{\sqrt{10} }{\sqrt{11} }$ * $\frac{\sqrt{11} }{\sqrt{11} }$ = $\frac{\sqrt{10} *\sqrt{11} }{\sqrt{11} *\sqrt{11} }$ = $\frac{\sqrt{110} }{11}$
