    monomials- just checking

    Right now i'm studying for a final (i know it seems like a weird time of the year, that's cuz i'm homeschooled ), and i'm coming across all these questions that I can't remember for sure how to do!

    I'm looking at this problem: (-3w^2n)(2n^2)^4
    I have to simplify it.
    I got -48w^2n^9, and I'm PRETTY sure it's correct. I just wanted to post this on here and double-check and make sure I didn't do something in the wrong order since it's been a while since I've done this!

    Here's how I did it:
    Original Problem = (-3w^2n)(2n^2)^4
    After First Step= (-3w^2n)(16n^8)
    After Next Step= -3*16*w^2*n*n^8
    After Last Step= -48w^2n^9


    I would appreciate your input. THANKS.

    Hello,

    your result is 100% correct. Congratulations!

    1 personal remark: I would use more brackets. For instance, I would print your answer as:

    I got -48(w^2)(n^9)
