HI!!

misty1212 · Answer

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

Hello

anonymous · Answer

No not really I don't understand

anonymous · Answer

Wait yes.

misty1212 · Answer

do you know what the square root means?

misty1212 · Answer

whew

misty1212 · Answer

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

anonymous · Answer

Okay.

anonymous · Answer

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

misty1212 · Answer

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

misty1212 · Answer

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

misty1212 · Answer

final answer 
$$2x\sqrt{14}$$
