Question 151642
Do you want to solve for "E"?


{{{c=0+-sqrt(E/m)}}} Start with the given equation.



{{{c^2=E/m}}} Square both sides



{{{mc^2=cross(m)(E/cross(m))}}} Multiply both sides by "m".



{{{mc^2=E}}} Simplify



{{{E=mc^2}}} Rearrange the equation



So the solution is {{{E=mc^2}}}

Do you want to solve for "m"?


{{{c=0+-sqrt(E/m)}}} Start with the given equation.



{{{c^2=E/m}}} Square both sides



{{{mc^2=cross(m)(E/cross(m))}}} Multiply both sides by "m".



{{{mc^2=E}}} Simplify



{{{m=E/(c^2)}}} Divide both sides by {{{c^2}}}.



So the solution is {{{m=E/(c^2)}}}
