f_{e}=x\times 40^{2}
Cancel out 2 and 2.
f_{e}=x\times 1600
Calculate 40 to the power of 2 and get 1600.
f_{e}=x\times 40^{2}
Cancel out 2 and 2.
f_{e}=x\times 1600
Calculate 40 to the power of 2 and get 1600.
x\times 1600=f_{e}
Swap sides so that all variable terms are on the left hand side.
1600x=f_{e}
The equation is in standard form.
\frac{1600x}{1600}=\frac{f_{e}}{1600}
Divide both sides by 1600.
x=\frac{f_{e}}{1600}
Dividing by 1600 undoes the multiplication by 1600.
