# How do you solve 3^(x^2) + 4x = 1/27?

$x \approx - 1.2 , - 0.26$
This is called a transcendental equation and therefore does not generally have a simple/exact solution. This is because of the x in the exponential and the coefficient. For example, ${e}^{x} = x$ doesn't have an analytical solution, just a numerical one.
