\[\frac{ 5 }{ \sqrt{30} }\]

multiply top and bottom by \(\sqrt{30}\)

then cancel the 5

Thank you!

Yup :P

Could you help me with one more?

Solve the equation. Identify any extraneous solutions.
√a = -2

we t solve for this you would square both sides..\[(\sqrt{a})^2=(-2)^2\]
a=4

\[\sqrt{4}=\pm2\]

Thanks!

You're welcome :)
