Problem 1 = x^3a * x^b my answer is x^3a+b
Problem 2 = 4ab(6a^2b^3) divide by -16a^3b^3 = 24a^3b^4 divided by -16a^3b^3 =
24b divided by 16 = -3b/2
Problem 3 = x^-3 = 1/x^3
Problem 4 = (-2x)^3 = 1/8x^3
Problem 5 = 2^-3 = 1/2^3 = 1/8

Question 1174031: Tony collects football cards. He has 123 cards now. He gave his friend 9 cards. Then he bought 5 more cards.
1. Write an equation to solve.
2. How many cards did he start with?
3. How many cards does he have now?
I believe this problem can be interpreted two different ways.
1. My Way: (123+9)-5=N Teacher: (123-9)+5=N
2. My Way: 132 Teacher: 119
3. My Way: 123 Teacher: 123
The question would thus be vague at best and it is my opinion that my way would actually be more literally correct as the question turns on past tense verbs after stating specifically how many cards he has now.
Kindly advise.
