Answer 9

I am confident that your teacher at least knows how to do it by hand

Answer 10

you can check your answer easily enough. does \[12\sqrt{6}*12\sqrt{6}=\sqrt{1008}\]? if so, then \[12*12*6=1008\]Does it?

Answer 11

no

Answer 12

its b

Answer 13

yes, b is correct because the factors of 1008 are 2,2,2,2,3,3,7

Answer 14

thnxs

Answer 15

1008 is even (ends in 0,2,4,6,8) so we can divide it by 2
504 is even so we can divide it by 2
252 is even so we can divide it by 2
126 is even so we can divide it by 2
63 has sum of digits of 9 so we can divide it by 3
21 has sum of digits of 3 so we can divide it by 3
7 can by divided by 7

1008 = 2*2*2*2*3*3*7
for each pair of identical factors under the square root sign, we can move them outside, keeping only 1, so
\[\sqrt{1008}=\sqrt{2*2*2*2*3*3*7}=2*2*3\sqrt{7}=12\sqrt{7}\]
