Question

Find \sqrt{(-4x+5)^2}

Answer 1

\[\sqrt{(-4x+5)^2} \]

Answer 2

the answer is (-4x + 5)

Answer 3

Actually I remember something with absolute value.. My question is:

Is it like this |-4x+5| or |4x+5| ?

Answer 4

the square root and the exponent 2 are vanish

Answer 5

i think you are right, it would be
\(|-4x+5|\)

Answer 6

idk, because if you multiply both equations, the answer is the same.
(-).(-) = (+)

Answer 7

you could write \[\pm(-4x + 5)\]

Answer 8

Yes, maybe.. I went to wolfram to check, got something weird http://www.wolframalpha.com/input/?i=sqrt%7B%28-4x%2B5%29%5E2%7D+++ :P Haha, thank youuuu =)

Answer 9

Answer 10
