Rationlise √ a + √ x/ √ a − √ x

Rationlise (sqrt(a)+sqrt(x))/(sqrt(a)-sqrt(x))

Rationlise (1)/(sqrt(7)+sqrt(3)-sqrt(2))

If 5{x}=x+[x] and [x]-{x}=(1)/(2) when {x} and [x] are fractional and integral part of x then x is

The solution set of the equation |[a+x, a-x, a-x], [a-x, a+x, a-x], [a-x, a-x, a+x]|=0 is

If {x} and [x] represent fractiona and integral part of x respectively then solve the equation x-1=(x-[x])(x-{x})

If a function f(x) is given by f(x)=(x)/(1+x)+(x)/((x+1)(2x+1))+(x)/((2x+1)(3x+1))+...oo then at x=0,f(x)

Using properties of determinants, solve for x:|[a+x, a-x, a-x],[ a-x, a+x, a-x],[ a-x, a-x, a+x]|=0

Using properties of determinants,solve |(x+a,x,x),(x,x+a,x),(x,x,x+a)|=0
