Answer 2

Okay 12 is 4*3, so:
sqrt(12)=sqrt(4*3)=sqrt(2*2*3)=2sqrt(3)

Answer 3

5*sqrt(12)=5*2sqrt(3) = 10sqrt(3)

Answer 4

10sqrt(3)-sqrt(3)=9sqrt(3)

Answer 5

\[10\sqrt{3}-\sqrt{3} = 9\sqrt{3}\]

Answer 6

\[\sqrt{12}\] can be written as \[\sqrt{4} \times \sqrt{3}\] however, as \[\sqrt{4}\] = 2

5\[\sqrt{12}\] = 5 x 2 √3

Therefore, 10√3−√3=9√3
