Thread: evaluation of an easy equation

hi,
with this question, I tried to solve it but I keep getting square root of -14 for the numerator. What am I doing wrong?!

question:

"Evaluate

√((−5)^2 − 3 + 14)
|19 − 6 + 3 − 25| "

thanks!

(−5)^2 = 25.

A minus times a minus is equal to a plus.
The reasons for this, we need not discuss.
