Question
Solve the equation
D=11313431
Alternative Form
D≈2.160944
Evaluate
D3×33+63=396
Use the commutative property to reorder the terms
33D3+63=396
Move the constant to the right-hand side and change its sign
33D3=396−63
Subtract the numbers
33D3=333
Divide both sides
3333D3=33333
Divide the numbers
D3=33333
Cancel out the common factor 3
D3=11111
Take the 3-th root on both sides of the equation
3D3=311111
Calculate
D=311111
