simplify

(2x^2y^2z)^2(x^4y)^5

I CAME WITH 4x^13y^9z^2 FOR THE ANSWER..

convert the number to scientifc notation

13,550,000,000

I CAME WITH 1.355x10^9 FOR THE ANSWER

**bobpursley**, Tuesday, December 16, 2008 at 9:42amOn the second, no. try 10^10. Think about that.

Now on the first, no.

expand the first part:

2x^2y^2z^2 squared

4x^4 y^4 z^4

Now the second part.

x^4 y to the fifth..

x^20 y^5

Now combine them by adding exponents.

**bobpursley**, Tuesday, December 16, 2008 at 10:49amNo. You are missing something.

the two to combine are:

(4x^4 y^4 z^4)(x^20 y^5)

Take the y exponents. What is 4+5?

When multiplying add the exponents. When taking to a power, multiply.

x^{3}* x^{k}=x^{3+k}

(x^{m})^{n}=x^{mn}
