6√5 + 2√5 - 7 = 8√5 - 7, which cannot be simplified.
2√20 - 3√7 - 2√5 + 4√63 = 2√(4 x 5) - 3√7 - 2√5 + 4√(9 x 7) = 4√5 - 2√5 - 3√7 + 12√7 = 2√5 + 9√7

Well, darling, 5 radical 7 is simply 5√7. It's like saying "5 times the square root of 7." So, there you have it, sweetie, nothing too crazy or radical about it. Just a little math fun to keep you on your toes!

5 radical 7. TO see this, let X = 5*radical(7) so X2 = 52*7 = 175 and let Y = radical(13) so Y2 = 13 175 is somewhat greater than 13 hence the answer.
6√5 + 2√5 - 7 = 8√5 - 7, which cannot be simplified.
2√20 - 3√7 - 2√5 + 4√63 = 2√(4 x 5) - 3√7 - 2√5 + 4√(9 x 7) = 4√5 - 2√5 - 3√7 + 12√7 = 2√5 + 9√7

sqrt(245) = sqrt(5*7*7) = 7*sqrt(5)

Zero. Zero divided by any number is zero.

8√12/5√4 = 8√(3*4)/5√4 = 8(√3)/5 = 8/5*√3
