Solution:
The image shows a mathematical equation to solve:\[ e^{4x} - 7x + 11 = 20 \]We want to solve for $$ x $$. To start, we can simplify the equation by moving all terms to one side to set the equation to zero.First, subtract 20 from both sides of the equation:\[ e^{4x} - 7x + 11 - 20 = 0 \]Now simplify:\[ e^{4x} - 7x - 9 = 0 \]This is a transcendental equation because it involves an algebraic part $$(-7x - 9)$$ and a transcendental part $$(e^{4x})$$. These equations are not typically solvable using elementary algebraic methods and often require numerical methods to find an approximate solution.Common numerical methods for solving transcendental equations include the Newton-Raphson method, the bisection method, or using software or graphing calculators.If an exact solution is not required, you could find approximate solutions using a graphing calculator or software by plotting the function \[ f(x) = e^{4x} - 7x - 9 \] and looking for the $$ x $$-values where $$ f(x) $$ crosses the $$ x $$-axis. These are the real roots of the equation.To solve this accurately, you would generally use a calculator or a computational tool that can handle transcendental equations.
