If |x-2|=5 then the value of x is

If f(x)={{:((sqrt(x^(2)+5)-3)/(x+2)",",x ne-2),(k,","x=-2):} is continuous at x=-2 , then the value of k is

If x^2-x+1=0 then the value of sum_[n=1]^[5][x^n+1/x^n]^2 is:

If "log"_(5)("log"_(5)("log"_(2)x)) =0 then the value of x, is

If |x^2-2x+2|-|2x^2-5x+2|=|x^2-3x| then the set of values of x is

If f(x) = (x - 1)(x - 2)(x - 3)(x - 4)(x - 5) , then the value of f' (5) is equal to

If 5(tan^2x - cos^2x)=2cos 2x + 9 , then the value of cos4x is
