सिद्ध कीजिए: `(4+3sqrt(-20))^(1//2)+(4-3sqrt(-20))^(1//2)=6`

Evaluate : (4+3sqrt(-20))^(1//2)+(4-3 sqrt(-20))^(1//2)

Prove that [4+ 3 sqrt(- 20)]^(1//2) +[4-3 sqrt(- 20)]^(1//2)= 6 .

Prove that : [4 + 3 sqrt(-20)]^((1)/(2)) + [4 -3 sqrt(-20)]^((1)/(2))= 6

Evaluate sqrt(4+3sqrt(-20))+sqrt(4-3sqrt(-20)) .

((2sqrt (45) + 3sqrt (20)) / (2sqrt (5))

sqrt(45)-3sqrt(20)+4sqrt(5)

Simplify : (3sqrt(-1)+sqrt(-2))div(2-sqrt(-4))

Prove (i) root3(20+14sqrt((2)))+root3(20-14sqrt((2)))=4 (ii) {6+sqrt((847)/(27))}^(1//3)+{6-sqrt((847)/(27))}^(1//3)=3
