In Algebra, always consider the signs, then the numbers, then the variables and their indices.

Explanation:

There are no negatives signs, the answer is positive.

Multiply the numbers as usual: 5 x 3 = 15

ADD the indices of like bases.

#m xxm^3 = m^4#

Anything to the power of zero equals 1, so we can ignore #n^0#
(but 6+0 = 6 anyway)

Put all this together in one answer: #15m^4n^6#
