Question

Simplify
sqrt(27) - sqrt(3) + 2[sqrt(12)]

Answer 1

sqrt(27)-sqrt(3)+2sqrt(12)
3sqrt(3)-sqrt(3)+4sqrt(3)
6sqrt

Answer 2

6sqrt(3)

Answer 3

\[\sqrt{3*9}-\sqrt{3}+2\sqrt{4*3}=3\sqrt{3}-\sqrt{3}+4\sqrt{3}=6\sqrt{3}\]

Answer 4

thanks :)

Answer 5

Simplify
[sqrt(36) - 4][sqrt(36) + 4]

Answer 6

is the 4 inside the radical?

Answer 7

If not then you will foil this
[sqrt(36)-4][sqrt(36)+4]
36-4sqrt(36)+4sqrt(36)-16, the -4sqrt(36) adn 4sqrt(36) cancel
36-16
20

Answer 8

yes

Answer 9

is that +20

Answer 10

Yes it is
