# How do you simplify (4a^2)(-3a)(-5a^4) using the product of powers property?

The result is $60 {a}^{7}$.
Then, we simply multiply the coefficient: $4 \setminus \cdot 3 \setminus \cdot 5 = 60$
Finally, we multiply the powers of $a$: the product of powers property says that if we multiply two powers of the same base, we simply have to sum up the exponents, so ${a}^{2} \setminus \cdot a \setminus \cdot {a}^{4} = {a}^{2 + 1 + 4} = {a}^{7}$.
