    Math test questions help:BASIC ALGEBRA AND EXPONENTS

    could someone give me the answers for these questions please (and the work if ur extra generous) these are the only questions that are troubling me ...


    kay. (when i put * and a number . ex: 4*3 it means 4 to the exponent 3)

    4x*2(xy*3)*2 + 3y*2 (x*2y*2)*2

    that looks confusing but once you write it out i dont think its that bad.
    it says simplify.

    and now the next one is quite long but.. id appreciate it!
    and it says Expand and simplify

    3xy*4(x*2 - 4xy + 7y*2) -5y*3(4xy*3 - 9x*3y) +14x*2y*5





    THANKS SO SO SO MUCH IF ANYONE HELPS ME OUT ON THIS ONE
