Answer 2

Answer:$-\sqrt{a}$

Step-by-step explanation:For Rationalising u need to multiply the number by the negative of the number.

For example 1/(2+$\sqrt{8}$)

To rationalise u need to multiply by 2-$\sqrt{8\\}$/2-$\sqrt{8}$

If u simplify that u get 2$-\sqrt{8}$

This is also called rationalising the denominator.

Hope this information helps u :)
