Value of the investment (loss of 13.8dollars)
48.48-13.8=34.65dollars
The logarithmic form of the equation y=loga x is equivalent to the exponential form x=ay. To rewrite one form in the other, keep the base the same, and switch sides with the other two values.
Ok so first, write down the equation. We know that x=3 and y=4. You just basically plug in the terms into the variables. So it would be 3(3)+1/4(4)^2. Simplify that equation and you should get your answer :)
