(3* square root of 2) square=  (3* square root of 2) * (3* square root of 2)

now lets remove the brackets

remember to multiply the number outside the square root; so gives us 3*3 =9

and then multiplythe number inside the square root; (square root of2 * square root of 2) = square root of 4

therefore, so far we have,

9* square root of 4

(as we already know, square root of 4 = 2)

so the final result will be to do: 9* 2 = 18
