Today we will understand how to identify, read, and write positive integer powers of nonnegative integers. Identify=to point out Positive integer=whole numbers greater than zero nonnegative numbers=positive numbers
Positive integer- a whole number greater than 0. Nonnegative integer- a whole number greater than 0. Power or Exponent- a mathematical notation indicating the number of times a quantity is multiplied by itself. –A power or exponent is placed to the right of and above another number.
