Answer:

#\sqrt(289)=\pm17#
Depends on if you actually need the #\pm# symbol, ask your teacher.

Explanation:

1. Use a calculator.

just kidding, I know that'd be too easy...

2. Factor out the number under the radical

That's the square root symbol.
#\sqrt(17\times17)#
Okay... that was fast. I guess your answer is #\pm17#, because #(\pm17)^2=289#
