    Solving exponential/rational inequality

    I am not sure what to do with this..

    Use your knowledge of exponents to solve the following.

    (1/2^x)>(1/x^2)

    I know this is an inequality problem where I have to find the intervals where one function is above the other.

    I am just lost at how to simplify the two

    You should graph these equations to discover the solutions.

    This question is similar to another question posted here:
