$\left(\sqrt{x-8}\right)^2=2^2$
Learn how to solve equations problems step by step online. Solve the equation (x-8)^(1/2)=2. Removing the variable's exponent raising both sides of the equation to the power of 2. Cancel exponents \frac{1}{2} and 2. Calculate the power 2^2. We need to isolate the dependent variable x, we can do that by simultaneously subtracting -8 from both sides of the equation.
