Homework Help: Algebra I

Posted by A on Friday, November 12, 2010 at 11:25am.

Hi, I would like someone to explain to me the process to get to the answer of these questions. (The answers are in the back of the book, but I don't understand how to get them myself):

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?

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")

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

Find and simplify the product of
a(-ab^2)^3 x (2a^2b^3)^2

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!
