Two questions:

27s(to the third power)t divided by 3st(to the sixth power)
.. my answer is 9s(squared)t(to the sixth)

4m(to the fifth power) times 6mn(squared)

My answer... 24m(to the sixth power)n(squared)

.. are these right? Thanks

Let me verify that the first question is like this:


\frac {27 s^3 t} {3 s t^6}


Is that right? If so, then your answer has an incorrect exponent for t, because:


\frac t {t^6} = \frac 1 {t^5}

The second one is correct: 4 m^5\cdot 6mn^2\ =\ 24 m^6 n^2

First one is not... its 9s(squared) divided by t(sixth power)
Second one... right...
