Who is asking: Student Question: How would I solve this equation? 1.6 = 2x/(.1x)  the equation in parenthesises is raised to the second power. I know you take the square root of both sides, but there is where I get lost. Thank you.Jenny Hi there, Taking the square root of both sides of 1.6 = 2x/(0.1x)^{2} is one way to begin solving this, but rather than do that, I would multiply both sides of the equation by (0.1x)^{2} to get rid of the rational expression on the right hand side. Next I would expand the square of (0.1x) to get 1.6 (0.01  0.2x + x^{2}) = 2x Now simplify, group all terms on one side so that it is set equal to zero and solve like any regular quadratic equation. If factoring the final form doesn't work, try using the quadratic formula. Hope this helps,Leeanne
