What is the square root of 50 + the square root of 8? Algebra Radicals and Geometry Connections Addition and Subtraction of Radicals 1 Answer Jim H Mar 26, 2015 #sqrt50+sqrt8=sqrt(25*2)+sqrt(4*2)# #=sqrt25sqrt2+sqrt4*sqrt2=5sqrt2+2sqrt3=7sqrt2#. Note #sqrt50# is also = #sqrt(5*10)# but I don't know either of those square roots, so: although it's true, it's not helpful. Answer link Related questions How do you add and subtract radicals?
