Adding Like Terms with Exponent Rules

Terms that have the same variable raised to the same exponent is called:

• like terms

• equations

• simplified terms

Why the result of adding 3b and -2b is just b and not b squared?

• Because you don't add exponents when adding like-terms

• Because the terms were not like-terms

• Because the terms have different coefficients

What is the rule for adding and subtracting monomials?

• add the exponents

• subtract the exponents

• multiply the exponents

• combine like terms and keep the exponents/variables the same

• the answer is always 1

• y¹⁴
• y¹⁰
• 1¹⁴
• 1¹⁰
