question? I don't see it there
it's just a value with a radical and a radicand
OpenStudy (jdoe0001):
not more of a question than say "2" or 53
OpenStudy (skittles_for_life6422):
oh whoops you have to simplify
OpenStudy (solomonzelman):
\(\color{black}{ \displaystyle -11\sqrt{112} }\)
how I visualized it: \(\color{black}{ \displaystyle 112=4\times (25+3) =4\times 28=4\times 4 \times 7 }\)
your hint from there: \(\color{black}{ \displaystyle 112=4^2\times 7 }\)
