First, simplify the square root of 32.

\(\sqrt{32}-7\sqrt2\\~\\ =\sqrt{2\cdot2\cdot2\cdot2\cdot2}-7\sqrt2 \\~\\ =\sqrt{2\cdot2}\cdot\sqrt{2\cdot2}\cdot\sqrt2-7\sqrt2 \\~\\ =2\cdot2\cdot\sqrt2-7\sqrt2 \\~\\ =4\sqrt2-7\sqrt2\)

4 cookies - 7 cookies = -3 cookies.

\(4\sqrt2-7\sqrt2=-3\sqrt2\)

So..the most simplified form is: \(-3\sqrt2\)

I did it using the LaTeX button right next to the image button...

Erase the stuff that is already inside and then click the " Math " button in the top left. At the bottom of the list there is a little picture of a square root. You can just click that and then type the number that you want to go underneath between the {} s.

Also..you can copy and pase this: √[ ]

And just type what goes under between the parenthesees :)

Or.....you can just type sqrt( )
