    2^4 = 16. 3^7 = 2187. 4^2 = 16.

    So you now have: (16 + 2187) / (729 - 16). 2203 / 713 = 3.09.

    If you realize that 729 = 3^6, then the problem is easy because it becomes-

    2^4 +3^1 - 4^2

    16 + 3 - 16

    (2^4 + 3^7) / (729 - 4^2)

    (16 + 2187) / ( 729- 16)

    (2203) / ( 713)

    3.0897...

    You could leave it as a fraction, or simplify it further and solve the fraction.

    16+2187 / 729-16

    2203 / 713

    That's algebra?

    Looks like simple math to me.

    Use a caculator.

    And if you ain't allowed to use one, you sure shouldn't be asking YA then, either.
