    It has to be (m+1)^2

    as m+1 > 1.

    For other anwer choices they are less than 1.

    m^3 should have the least value

    For 0 < m < 1,
    1 > m > m^2 > m^3

    The other 2 are greater than 1. So, m^3 is the least of the lot

    The answer is m^3

    Try and substitute values for m and it'll be easy. Let's say m=.5

    Therefore .5^2= .25
    .5^3=.125
    2-.5=1.5
    .5+1= 1.5
    Hence m^3 is the smallest
