When you have a power to a power, what operation should you do with the powers? Example: (x3)4
Multiply the powers
Simplify: (4x3y2)(5xy6)
20x4y8

Three
Simplify: (2x3)3
8x9
Write an example of a polynomial with 4 terms and degree of 3.
I'll check!
Simplify:(2x3z6)(6x3z-2)
12x6z4
Like terms need to have...(two things!!)
1. Same variables 2. Same exponents
(6x3+4x2-4x+5)-2(2x3-3x2+5x-5)
2x3+10x2-14x+15
