Sagot :

5x to the fourth is the first one

Answer:

Step-by-step explanation:

Commutative propriety really means you can change (commute) the order you add or multiply numbers and the result will be the same

ab = ba

x+18 = 18+ x

Associative propriety means you can add in any order

3+(a+b) = (3+a) + b

Combine like terms is 8 of something - 3 of the same thing is 5 of something

8x^4  - 3x^4 = 5x^4

only the terms with b are the same kind

9b+ 4b -14 = 13b -14
