15a^3b^4c^5----> answer B
you can only multiple like terms so
(5x3)= 15
now just add
a+a^2= a^3
b + b^3 = b^4
c^5 + 0= c^5
Order of Operations:
1. Parentheses
2. Exponents

Step-By-Step Explanation:
1. Take 9 • 11 = 99
2. Take 10 / 2 = 5
3. Take 2 + 10 - 99 = -87
So -87 would be your final answer. Hope that helped!
