what is the answer to simplifying this equation:

25a^-2 b^-5 c^8/40 a^5 c^9

  • prealgerbra -

    (25a^-2 b^-5 c^8)/(40 a^5 c^9)

    I made changes assuming that is what you meant.
    = 5/(8a^7 b^5 c)

    Usually, it is considered simplified if no negative exponents are hanging around.
    check with your teacher what they consider "simplified"
