Explain the fallacy
`-1=ixxi=sqrt-1xxsqrt-1=sqrt((-1)xx(-1))=sqrt1=1.`

If x=sqrt(1+sqrt(1+sqrt(1+...))) , then

int sqrt((1+x)/(1-x)) dx =

The equation sqrt(x+1)-sqrt(x-1)=sqrt(4x-1) has

The domain of the function f(x)=sqrt(1-sqrt(1-sqrt(1-x^2))) is :

Solve sqrt(x+3-4sqrt(x-1))+sqrt(x+8-6sqrt(x-1))=1

lim_(x rarr 1) (sqrt(x-1) + sqrt(x-1))/(sqrt(x^(2)-1)) =

(sin^(-1)x)/(sqrt(1+x))dx=

If three unequel numbers are in HP and their squares are in AP, show that they are in the ratio 1+sqrt(3):-2:1-sqrt(3) " or " 1-sqrt(3):-2:1+sqrt(3) .
