Question

Subtracting a radical? Please help me!!!!!

(7- √54) - (5 + √24)

Answer 1

\(\sqrt{54}=\sqrt{3*3*6}\)
\(=3\sqrt{6}\)
\(\sqrt{24}=\sqrt{2*2*6}\)
\(=2\sqrt{6}\)
\(7- \sqrt{54} - (5 + \sqrt{24})\)
\(=7-3\sqrt{6}-5-2\sqrt{6}\)
\(=7-5-3\sqrt{6}-2\sqrt{6}\)
Can u do it @InsanelyChaotic?

Answer 2

I'm attempting

Answer 3

The answer would be \[2 - \sqrt{6}\]

Answer 4

First part of ur answrer is right
