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

simplify

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

x^{2} + y^{2}

Solution steps

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

Apply radical rule:

a = a a

x^{2} + y^{2} = x^{2} + y^{2} x^{2} + y^{2}

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

Cancel the common factor:

x^{2} + y^{2}

= x^{2} + y^{2}

\frac{2}{x + 1} + \frac{x}{x + 1}

(4 x + 1)^{3}

1 5^{3}

\frac{- 4 ( x ^{2} - 1 ) ^{2} + 4 x \cdot 2 ( x ^{2} - 1 ) 2 x}{( x ^{2} - 1 ) ^{4}}
