Adding and Subtracting Bases with Exponents Explained

This video tutorial covers the basics of adding and subtracting exponents. It explains the importance of having the same base and exponent when performing these operations. The tutorial provides examples and practice problems to illustrate the concepts, emphasizing that only coefficients are combined while bases and exponents remain unchanged.

What must be identical for adding or subtracting terms with exponents?

• Only the exponents

• Only the bases

• The coefficients

• Both the bases and the exponents

Can 4x to the 4th and 7x to the 4th be combined?

• No, because they represent different values

• Yes, but only the exponents are added

• No, because the coefficients are different

• Yes, because the bases and exponents match
