simplify (sqrt(x^2+y^2))/(sqrt(20-(x^2+y^2)))

simplify

\frac{x ^{2} + y ^{2}}{20 - ( x ^{2} + y ^{2} )}

\frac{x ^{2} + y ^{2}}{20 - x ^{2} - y ^{2}}

Solution steps

\frac{x ^{2} + y ^{2}}{20 - ( x ^{2} + y ^{2} )}

Apply radical rule:

\frac{a}{b} = \frac{a}{b}

\frac{x ^{2} + y ^{2}}{20 - ( x ^{2} + y ^{2} )} = \frac{x ^{2} + y ^{2}}{20 - ( x ^{2} + y ^{2} )}

= \frac{x ^{2} + y ^{2}}{20 - ( x ^{2} + y ^{2} )}

- (x^{2} + y^{2}) : - x^{2} - y^{2}

= \frac{x ^{2} + y ^{2}}{20 - x ^{2} - y ^{2}}
