Answer 1

HI!!

Answer 2

is it clear that \(\sqrt{x^2}=x\)?

Answer 3

Hello

Answer 4

No not really I don't understand

Answer 5

Wait yes.

Answer 6

do you know what the square root means?

Answer 7

whew

Answer 8

so the \(x\) comes outside of the radical
now lets deal with \(\sqrt{56}\)

Answer 9

Okay.

Answer 10

Do we have to find the factors of it or something like that

Answer 11

\[56=4\times 14\] so
\[\sqrt{56}=\sqrt{4\times 14}=\sqrt4\sqrt{14}=2\sqrt{14}\]

Answer 12

yeah find the perfect square that is a factor of 56
in this case it is 4

Answer 13

final answer
\[2x\sqrt{14}\]

Answer 14
