simplify 1/(sqrt(x^2+y^2+z^2))

simplify

\frac{1}{x ^{2} + y ^{2} + z ^{2}}

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

Solution steps

\frac{1}{x ^{2} + y ^{2} + z ^{2}}

Multiply by the conjugate

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

= \frac{1 \cdot x ^{2} + y ^{2} + z ^{2}}{x ^{2} + y ^{2} + z ^{2} x ^{2} + y ^{2} + z ^{2}}

1 \cdot x^{2} + y^{2} + z^{2} = x^{2} + y^{2} + z^{2}

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

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

x^{2} + 4 x - 5 x + x^{2}

0 + (- 3)

(7 - 3)^{2}
