In this lesson, we will learn what an exponent is in math and how to calculate exponents. An exponent is a shorthand way of writing multiplication. We take a number called the base, and raise it to a power, which is called the exponent. The base is then multiplied by itself the number of times as is given by the exponent. Exponents are used very often in physics, math, and engineering, because most equations such as gravity, equations of motion, and the like have exponents in the equation. We will learn how to write exponents, how to write the exponent as the product of factors, and how to calculate the value of the exponent for the answer. In future lessons, we will learn how to multiply terms with exponents and how to divide terms that have exponents.
