QUESTION ONE

Warren has 40 coins (all nickels, dimes, and quarters) worth $4.05. He has 7 more nickels than dimes. How many quarters does Warren have?

QUESTION TWO

Find and simplify the sum of a^2(ab^3)^2, b^2(a^2b^2)^2

("^2" means "exponent of two" or "to the second power")

QUESTION THREE

Find and simplify the sum of

a(-ab^2)^3 + (2a^2b^3)^2

QUESTION FOUR

Find and simplify the product of

a(-ab^2)^3 x (2a^2b^3)^2

QUESTION FIVE

Show that 16^x times (4^x)^2 = (2^x)^8

I would really, really appreciate any help for any of the questions. I am trying so hard but I just don't get it!

N = D + 7

25Q + 10D + 5N = 405

25Q + 10D + 5(D+7) = 405

2. (ab^3)^2 = a^2(b^6), assuming that only the b term is cubed. Power to a power is simplified by multiplying.

That should help you with the other problems too.
