Question

What is the quotient in simplified form? State any restrictions on the variable.

Answer 1

Restriction on the variable.

The variable is restricted saying that it can NOT equal something, when this "something" makes the square root equal zero.

Answer 2

factor top and bottoms of both fractions, and then use,
\(\Large\color{black}{ \rm \frac{r}{n} \div \frac{a}{v}= \frac{r}{n} \times \frac{v}{a} }\)
and then cancel some terms out.

Then we will get to restrictions.
