I do not understand how to set this up, let alone figure it out. Any help is very appreciated. Thank you.

Einsteins famous formula E=mc^2 related energy E, mass M, and the speeds light C. Express the formula by solving for C in terms of E and M and rationalize the denominator .

    Start with E = mc^2, and solve for c. Divide both sides by m:

    E/m = c^2

    Take the square root of both sides and simplify a bit:

    (E/m)^0.5 = c

    E^0.5 / m^0.5 = c

    Multiply by m^0.5 / m^0.5 to rationalize the denominator, then simplify the numerator:

    (E^0.5 * m^0.5) / m = c

    (Em)^0.5 / m = c
