SOLUTION: how would i solve for m the equation 2m^3=54, i am guessing it should start off with 2m^3-54=0 then, 2(m^3)=2(-27)=0, but then i get totaly lost and confused any help please

You can put this solution on YOUR website! 2m^3=54
divide both sides by 2:
m^3=27
take the "cube root" of both sides:
m = cubeRt(27)
factor to prime numbers:
m = cubeRt(3*3*3)
m = 3
