= √3 + √27

= √3 + √(9 * 3)

= √3 + (√9 * √3)

= √3 + (√3² * √3)

= √3 + (3 * √3)

= √3 + 3√3

= 4√3

√3 + √27

Simplify the square root of 27, knowing that you can factor a 9 out of it which is a perfect square to get:

√3 + √(9 * 3)

√3 + 3√3

Now you can combine like terms to get:

4√3

It is the same as (1 times square root of 3 )+ (3 times the square root of 3) = 4 times square root of 3

How to do what? What do you want done with the expression?

The expression can be written in a simpler form if you recognize that √3 is a factor of both terms.

√3 + √(3*9)

= √3 + 3√3

= 4√3
