Answer

No solution

Work Step by Step

Given \begin{equation} \begin{aligned} & \sqrt{x}+4=2 \\ & {[-2,18,1] \text { by }[0,10,1]} \end{aligned} \end{equation} Let \begin{equation} \begin{aligned} f(x)&= \sqrt{x}+4\\ g(x)&=2\\ \end{aligned} \end{equation} The plots of the two functions are shown in the figure. We see that there is no point of intersection between the graphs of the functions and so, no solution to the radical equation.
