If `x^3=a+1` and `x+b/x=a`, then x equals to

If 3^x=4^(x-1) , then x equals

If 3^x=4^(x-1) , then x equals

If 3^x=4^(x-1) , then x equals

If x-1/x=7 , then x^3-1/x^3 is equal to :

If 3^(x)-3^(x-1)=18 , then x^(x) is equal to

For the function f(x)={((x^(3)-a^(3))/(x-a)",",x ne a),(b" ,",x =a):} , if f(x) is continuous at x = a, then b is equal to
