solve each 1st degree equations with radicals (square root of x-8)=2

OpenStudy (anonymous):

$\sqrt{x-8} =2$

OpenStudy (anonymous):

simple square both sides

OpenStudy (saifoo.khan):

$x-2 = 2^2$

OpenStudy (anonymous):

Square both sides to get rid of the radical $(\sqrt{x-8})^2 = 2^2$ Squaring a radical cancels out the radical leaving you with $x - 8 = 4$ Solve for x $x = 12$
