2\times 4\times 5=8\sqrt{5}x
Multiply \sqrt{5} and \sqrt{5} to get 5.
8\times 5=8\sqrt{5}x
Multiply 2 and 4 to get 8.
40=8\sqrt{5}x
Multiply 8 and 5 to get 40.
8\sqrt{5}x=40
Swap sides so that all variable terms are on the left hand side.
\frac{8\sqrt{5}x}{8\sqrt{5}}=\frac{40}{8\sqrt{5}}
Divide both sides by 8\sqrt{5}.
x=\frac{40}{8\sqrt{5}}
Dividing by 8\sqrt{5} undoes the multiplication by 8\sqrt{5}.
x=\sqrt{5}
Divide 40 by 8\sqrt{5}.
