HW #4 (801 & 802) more like terms!

For homework this evening you'll have another small worksheet on combining like terms. Remember when you are multiplying and the bases are the same add the exponets and keep the base. For example:
(note, ^ means to raise that base to the power)
y^2 * y^5
y * y * y * y * y * y * y
y^7

2x^3 * 3y^4 * 5 x^2
2 * x * x * x * 3 * y * y * y * y * 5 * x * x
2 * 3 * 5 * x^5 * y^4
30 * x^5 * y^4

Many apologies about the ^! This program doesn't allow me to superscript.
