Simplify..?

OpenStudy (anonymous):

\[(2\sqrt{5} +3\sqrt{7}^2\]

OpenStudy (anonymous):

and yess c:

OpenStudy (anonymous):

assuming theres another parentheses in there?

OpenStudy (anonymous):

yes lol at the end

OpenStudy (anonymous):

\[(2\sqrt{5} + 3\sqrt{7})(2\sqrt{5}+3\sqrt{7})\] you're going to foil which means first times first +firsttimes 2nd + 2nd times first + 2 times 2nd which gives you \[(4*5)+6\sqrt{35}+6\sqrt{35}+(9*7)\] I will let you simplify from there
