Answer:
-64a^13 :)
I hope this helped you a bit!
Step-by-step explanation:
Apply the product rule to 4a^3.
-4^3 (a^3)
Raise -4 to the power of 3.
-64 (a^3)^3*a^4
Multiply the exponents in (a^3)^3.
Apply the power rule and multiply exponents
-64a^3*3*a^4
Multiply 3 by 3.
-64a^9*a^4
Multiply
a^9
by a^4
by adding the exponents.
Move a^4
-64 (a^4 a^9)
Use the power rule to combine exponents
-64a^4+9
Add 4 and 9.
-64a^13
