Summary:В Whole numbers can be expressed in standard form, in factor form and in exponential form. If a number is raised to the third power, we say it is cubed. If a number is raised to the second power, we say it is squared. The following rules apply to numbers with exponents of 0, 1, 2 and 3: RuleДЄny number (except 0) raised to the zero power is equal to 1.ДЄny number raised to the first power is always equal to itself. Solution:В 8 x 8 x 8 x 8 x 8 x 8 x 8 = 8 7 8 raised to the seventh powerД®xample 5:В Write 10 3, 3 6, and 1 8В in factor form and in standard form. Solution:В 6 x 6 x 6 x 6 x 6 = 6 5 6 raised to the fifth powerД®xample 4:В Write 8 x 8 x 8 x 8 x 8 x 8 x 8 using exponents, then read your answer aloud. Solution:В 3 x 3 x 3 x 3 = 3 4 3 raised to the fourth powerД®xample 3:В Write 6 x 6 x 6 x 6 x 6 using exponents, then read your answer aloud. Let's look at some examples of writing exponents where the base is a number other than 2.Д®xample 2:В Write 3 x 3 x 3 x 3 using exponents, then read your answer aloud. So far we have only examined numbers with a base of 2. Let us take another look at the table from above to see how exponents work. Solution:В 2 x 2 x 2 x 2 x 2 = 2 5 2 raised to the fifth power Read as two raised to the millionth powerД®xample 1:В Write 2 x 2 x 2 x 2 x 2 using exponents, then read your answer aloud. We write this number in exponential form as follows: The exponentВ tells us how many times the baseВ is used as a factor.ДЇor example, to write 2 as a factor one million times, the base is 2, and the exponent is 1,000,000. Exponential notation is an easier way to write a number as a product of many factors. A better way to approach this is to use exponents. Writing 2 as a factor one million times would be a very time-consuming and tedious task. How long do you think that would take? Answer. Suppose that your teacher asked you to Write 2 as a factor one million timesВ for homework. The product of factors is also displayed in this table. In the table below, the number 2 is written as a factorВ repeatedly. Learn about the rules of exponents with the following examples and interactive exercises.
