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}}

e^{3} \cdot e^{9}

(x + 2)^{2} \cdot (x - 1)^{2}

(b + a)^{2} \cdot (b - a)^{2}

- e^{- x} \cdot 9 e^{- 3 x}
