-3sqrt(147)-(7)/(3)sqrt((1)/(3))+7sqrt((1)/(3))

(3+sqrt(7))/(3-sqrt(7))

Simplify : 7sqrt((1)/(3)) -2(1)/(3) sqrt((1)/(3)) +3 sqrt( 147)

Simplify. (4)/(7)sqrt(147)+(3)/(8)sqrt(192)-(1)/(5)sqrt(75)

(7+3sqrt(5))/(3+sqrt(5))+(7-3sqrt(5))/(3-sqrt(5))

(3 + sqrt7)(3 - sqrt7)

Simplify: (7+3sqrt(5))/(3+sqrt(5))-(7-3sqrt(5))/(3-sqrt(5)) (ii) (1)/(2+sqrt(3))+(2)/(sqrt(5)-sqrt(3))+(1)/(2-sqrt(5))

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))

The number (7+5sqrt(2))^((1)/(3))+(7-5sqrt(2))^((1)/(3)) ,is equal to

(3+sqrt(7))/(3-sqrt(7))=a+b sqrt(7)
