sqrt7 - 3/5 sqrt7 + 2sqrt7

( sqrt3 + sqrt7)^2

Add 2sqrt2+5sqrt3 and sqrt2 - 3 sqrt3

(sqrt3 + sqrt7)^2

Add: (3sqrt3-sqrt2+sqrt5) and (2sqrt2+5sqrt3-7sqrt5)

Add (i) (2sqrt(3)-5sqrt(2)) and (sqrt(3) + 2sqrt(2)) (ii) (2sqrt(2) + 5sqrt(3) - 7 sqrt(5) and (3sqrt(3)-sqrt(2) + sqrt(5)) (iii) ((2)/(3) sqrt(7) -(1)/(2)sqrt(2)+6sqrt(11)) and ((1)/(3)sqrt(7) + (3)/(2)-sqrt(11))

Add 2sqrt2+ 5sqrt3 and sqrt2- 3sqrt 3 .

If x= ( sqrt5- sqrt3)/ ( sqrt5+ sqrt3) and y= ( sqrt5+ sqrt3)/( sqrt5- sqrt3) find the value of x^(2) + y ^(2)

Add 2sqrt2+5sqrt3 and sqrt2-3sqrt2
