Homework Help: Simple exponent question

  1. Sep 18, 2006 #1
    Hi I am currently doing this problem and ran into a fork in the road-

    6ab - 2b2 / 12ab - 4b2

    I got .5ab + .5b2 as my answer. Now I am wondering if the second part is right cuz I am not sure if -2b2 / -4b2
    is either .5b2 or just 1.. cuz the exponents 2-2= 0 and anything with the exponent of 0 equals 1 right?

    Some help would be appreciated.

    If its (6ab - 2b^2) / (12ab - 4b^2)

    pull out the common multiples from the numerator and dominator

    also .5b^2 and 1 dont work

    yes anything with exponent of 0 equals one you then multiply that one with -2 / -4,... the same way any number divided that number is one except zero yada yada yada...
