Answer 1

@MathLegend please help

Answer 2

With the first one... we can combine like terms...

Just like you can combine a 4x and a 2x...

4x + 2x = 6x

You can combine terms that have the same number under the radical... so I will help you with the 1st worksheet and you do the other ones based off what we do.

Answer 3

\[5\sqrt{7}-10\sqrt{7} = -5\sqrt{7}\]

Answer 4

So can you combine the ones with the Radical 6? we have...

Answer 5

\[12\sqrt{6}-5\sqrt{6} = ?\]
