Question

$$\frac{ -20 }{ \sqrt{ 3-1 } }$$

Evaluate

$-10\sqrt{2}\approx -14.142135624$

Solution Steps

Subtract $1$ from $3$ to get $2$.

$$\frac{-20}{\sqrt{2}}$$

Rationalize the denominator of $\frac{-20}{\sqrt{2}}$ by multiplying numerator and denominator by $\sqrt{2}$.

$$\frac{-20\sqrt{2}}{\left(\sqrt{2}\right)^{2}}$$

The square of $\sqrt{2}$ is $2$.

$$\frac{-20\sqrt{2}}{2}$$

Divide $-20\sqrt{2}$ by $2$ to get $-10\sqrt{2}$.

$$-10\sqrt{2}$$
