सिद्ध कीजिए कि :
`sqrt(8+6i)-sqrt(8-6i) = 2i`

यदि triangleABC में (If इन triangleABC), a = (1)/(sqrt(6)-sqrt(2)), b = (1)/(sqrt(6)+sqrt(2)), C = 60^(@) तो सिद्ध कीजिए कि (Prove that) c = (sqrt(4))/(2) .

(2sqrt8)/(sqrt6-sqrt2)=

सिद्ध कीजिए कि 2tan^(-1)sqrt((b)/(a))=cos^(-1)((a-b)/(a+b))

Evaluate: sqrt(-8i)

(sqrt(3)+i)^(6)+(sqrt(3)-i)^(6)=

[(sqrt(5)+i/2)(sqrt(5)-i2)]-:(6+i5)

Evaluate sqrt(6 + 8i) .

If y=sqrt(x^2+6x+8) then show that one of the value of sqrt(1+iy)+sqrt(1-iy) is sqrt(2x+8) (i=sqrt(-1))
