Understanding Powers and Exponents

The video tutorial by Mrs. C from Math Defined explains how to use a scientific calculator to find powers and exponents. It covers the use of specific calculator buttons, such as the x squared, caret, fraction, and negative sign buttons. The tutorial provides step-by-step examples for calculating 3 squared, 3 to the 5th power, 4 to the one-half power, and 10 to the negative 2 power. The video concludes with a call to action for viewers to subscribe and leave comments.
