Simplify (5ab4c) (-abc2).

For simplification of the given above, multiply the numerical coefficients and variables of the first factor to corresponding items on the second factor. This is shown below.

5 x - 1 = - 5

a x a = a²

b^4 x b = b^5

c x c² = c³

Thus, the simplified product is - 5a² (b^5) c³
