Please help!<br>I know it's probably simple, but I don't understand...
kifflom [539]
For the reciprocal, you swap numerator and denominator.

a. The reciprocal of \frac{\sqrt{2}}{2} is \frac{2}{\sqrt{2}}
To rationalize the irrational denominator, multiply numerator and denominator by the radical, then simplify.
=\frac{2 \times \sqrt{2}}{\sqrt{2} \times \sqrt{2}} = \frac{2 \sqrt{2}}{2} = \sqrt{2}

b. \frac{-2}{\sqrt{3}} = \frac{-2 \sqrt{3}}{3}
