Answer:

An exponential function and a polynomial are mixed in this equation. It is easy to frame such an equation like #a^x=bx+c# that is solvable by inspection. Here, the solution is x = 2.

Explanation:

Only numerical iterative methods help solving equations like #a^x=bx+c#. The methods generate a sequence of approximations #{x_n}, n=0, 1,2,3...,# with # x_n to x#, as #n to oo#.

A starter approximate solution #x_0# is required for using such methods. Newton Raphson method is one such method..
