Answer 1

square root 27 is 3squer root 3 so the answer is 2 square root three

Answer 2

We want to combine the two given radicals to simplify the expression, we will get:

√27- √3 = 2*√3

Working with the expression.

So we start with:

√27- √3

Here you can remember that 27 = 3*9, so we can rewrite:

$\sqrt{27} = \sqrt{3*9} = \sqrt{3}*\sqrt{9}$

And we know that √9 = 3, so we have:

√27 = 3*√3

Then we can rewrite our expression as:

√27 - √3 = 3*√3 - √3 = 2*√3
