What is x times x?
In this video we look at the reason why x times x is x raised to the power 2, also known as x squared. The key to this lesson is to realize that an exponent tells us to multiply a number by itself a certain number of times. For example, the base 5 with an exponent 3 means multiplying 5*5*5. In other words, multiply 5 by itself 3 times.
