If `1/5-x=4/5`, then the value of x is

In Figure, if y/x=5 and z/x=4, then the value of x is

If sin^(-1)(x/5) + cosec^(-1) (5/4) = pi/2 , then the value of x is

If sin^(-1)(x/5)+cose c^(-1)(5/4)=pi/2 then the value of x is: (1) 1 (2) 3 (3) 4 (4) 5

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

If f(x)=int((5x^4+4x^5))/((x^5+x+1)^(2))dx and f(0)=0, then the value of f(1) is :

If x+1/x=sqrt(5) , find the values of x^2+1/(x^2) and x^4+1/(x^4)

Let f(x^(3)) = x^(4) + x^(5) + x + 1 , then the value of f(8) is

If f(x) is an invertible function and g(x)=2f(x)+5, then the value of g^(-1)(x)i s (a) 2f^(-1)(x)-5 (b) 1/(2f^(-1)(x)+5) 1/2f^(-1)(x)+5 (d) f^(-1)((x-5)/2)

If f(x) is an invertible function and g(x)=2f(x)+5, then the value of g^(-1)(x)i s (a) 2f^(-1)(x)-5 (b) 1/(2f^(-1)(x)+5) 1/2f^(-1)(x)+5 (d) f^(-1)((x-5)/2)
