Sqrt(20) = sqrt(5)*sqrt(4) = 2*sqrt(5)

just round off the number after the decimal if it is above 5.

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

It is an expression that can be simplified to: 3x-20

5/(8 + âˆš7) = (40 - 5âˆš7)/57 is the rationalised equivalent.
