If `2x -3 =7 -5x`, then x is ______.

If 2^(x).9^(2x+3) = 7^(x+5) , then x =

If 2^(x).9^(2x+3) = 7^(x+5) , then x =

If x/4 lt (5x-2)/3 -(7x-3)/5, x in R then

Add: 7x, -3x, 5x, -x, -2x

If f(x) = 2x^(3)+7x-5 and g(x) = f^(-1)(x) , then reciprocal of g^(')(4) is equal to

Let f: R rarr R be defined as f(x)=2 x^3+7 x-5 and g(x)=f^-1(x) . If g^prime(4)=a/b where a and b are relatively prime positive integers then (a+b) is equal to
