Question

Ok, so I don't think I can simplify this any further...am I right or wrong? -72a^5b^4/-12ab^2.

Answer 1

I am afraid you are rather incorrect. You can cancel the negative signs, divide 72 by 12, divide a^5 by a, and divide b^4 by b^2 ...
\[ \frac{-72a^5b^4}{-12ab^2} = 6a^4b^2\]

Answer 2

I did come up with 6a^6b^6 but didn't think that was right, I was having a hard time beyond 72/12.
Thanks for your help!
