    Welcome to PF.

    Not sure your method, but I get something different.

    Plugging in your value I get 4.096 = 4.32

    Maybe try taking the square root of both sides of

    (1+x)2 = 4.32/3.13

    And then solving simply?

    To solve this correctly you need to expand and simplify and then use the quadratic formula to find x. There are two solutions to this equation.
