Negative Exponents In this tutorial, we will learn about negative exponents. When we change a negative exponent into positive exponent, we write the reciprocal of the given positive exponent. Negative sign means the reciprocal of the given number. For any non zero number a, (a-m = 1/am). Where m is a positive integer and a-m […]
