What is an Exponent

Exponents

An exponent is a positive or negative number placed above and to the right of a quantity. It expresses the power to which the quantity is to be raised or lowered. In 4³ , 3 is the exponent. It shows that 4 is to be used as a factor three times: 4 × 4 × 4 (multiplied by itself twice). 4³ is read as four to the third power (or four cubed).
Remember: x¹ = x and x^{0 = 1 when x is any number (other than 0).}
