# Equation - Cant figure out how to rearrange the equation to solve for M

Original equation is :

D= rt/6(3.14=pi)VN * cubed root of 4(pi)N/3Mu

need to get m= from the above equation and I am stuck. could yo show step by step how to solve for M.

thank-you

Parentheses show which parts of the equation should be grouped together. However, two sections of the equation can be combined (regardless of where is parentheses should go), and considered as single variables. 1st part = rt/6(3.14=pi)VN 2nd part = cubed root of 4(pi)N Once these changes have been made, the equation becomes: D= (1st part) * (2nd part)/3Mu The notation still leaves you with three possibilities 1st Possibility: D = (1st part) * (2nd part)*(1/3)*Mu or 2nd Possibility: D = (1st part) * (2nd part)*[1/(3*M)]*u or 3rd Possibility: D = (1st part) * (2nd part)*[1/(3*M*u)] -------------------------------------------------- Solving for M: 1st Possibility: D= (1st part) * (2nd part)*(1/3)*Mu D = (1st part) * (2nd part)*(1/3)*Mu D / {(1st part) * (2nd part)*(1/3)} = {(1st part) * (2nd part)*(1/3)*Mu} / {(1st part) * (2nd part)*(1/3)*u} D / {(1st part) * (2nd part)*(1/3)*u} = M M = D / {(1st part) * (2nd part)*(1/3)*u} >>> M = D / {( rt/6(3.14=pi)VN) * (cubed root of 4(pi)N)*(1/3)*u} -------------------------------------------------- Solving for M: 2nd Possibility: D = (1st part) * (2nd part)*[1/(3*M)]*u D = (1st part) * (2nd part)*[1/(3*M)]*u D*M = {(1st part) * (2nd part)*[1/(3*M)]*u}*M D*M = {(1st part) * (2nd part)*(1/3)*u} D*M / D = {(1st part) * (2nd part)*(1/3)*u} / D M = {(1st part) * (2nd part)*(1/3)*u} / D >>> M = {(rt/6(3.14=pi)VN) * (cubed root of 4(pi)N)*(1/3)*u} / D -------------------------------------------------- Solving for M: 3rd Possibility: D = (1st part) * (2nd part)*[1/(3*M*u)] D = (1st part) * (2nd part)*[1/(3*M*u)] D*M = {(1st part) * (2nd part)*[1/(3*M*u)]}*M D*M = {(1st part) * (2nd part)*[1/(3*u)]} D*M / D = {(1st part) * (2nd part)*[1/(3*u)]} / D M = {(1st part) * (2nd part)*[1/(3*u)]} / D >>> M = {( rt/6(3.14=pi)VN) * (cubed root of 4(pi)N)*[1/(3*u)]} / D Thanks for writing.
