Chapter 7 - Exponents and Exponential Functions - Chapter Test: 21

Answer

The student multiplied the bases, which is not required and is incorrect.

Work Step by Step

To multiply powers with the same base, we add the exponents. We do not do anything to the bases. Therefore, the student should have written $3^4\times3^3=3^7$ instead of $3^4\times3^3=9^7$.
