2a to the second power. If you combine the like terms, (a to the second power + a to the second power), it would be the same as 2a to the second power.
Like terms
They are 'like' terms
Like terms are terms with the same variable to the same power. Examples: 2y and 3y are like terms. 2y and 2z are not like terms 4y squared and 3y squared are like terms 4y squared and 3y are not like terms

2a to the second power. If you combine the like terms, (a to the second power + a to the second power), it would be the same as 2a to the second power.
For the expressions: 2d 5d2 4x2 d2 6x The like terms wold be 5d2 and d2 If you were to add all of those terms together, they would be: 6d2 + 4x2 + 2d + 6x
The last one is an example of like terms.

Like terms are terms with the same variable to the same power. Examples: 2y and 3y are like terms. 2y and 2z are not like terms 4y squared and 3y squared are like terms 4y squared and 3y are not like terms
They are terms in which a variable is raised to the same power (index) in both terms. So x2y and -27x2y are like terms but not xy2.
452 and 622 are like terms. 452 - 622 = -172.
