After you click ENTER, a message will appear in the RESULTS BOX to indicate whether your answer is correct or incorrect. Do not use commas in your answers, just digits. Step 3: Multiply the given digit by its place value and represent the number in the form of (digit × place value). Step 2: Identify the place value of the given number using the place value chart. Click once in an ANSWER BOX and type in your answer then click ENTER. Go through the below steps to write the numbers in expanded form: Step 1: Get the standard form of the number. The exponent tells us how many times the base is used as a factor.ĭirections: Read each question below. A number written in exponential form is a base raised to an exponent. Exponential notation makes it easier to write a number as a factor repeatedly. Summary: 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: RuleĪny number (except 0) raised to the zero power is equal to 1.Īny number raised to the first power is always equal to itself. Solution: 8 x 8 x 8 x 8 x 8 x 8 x 8 = 8 7 8 raised to the seventh powerĮxample 5: Write 10 3, 3 6, and 1 8 in factor form and in standard form. Solution: 6 x 6 x 6 x 6 x 6 = 6 5 6 raised to the fifth powerĮxample 4: Write 8 x 8 x 8 x 8 x 8 x 8 x 8 using exponents, then read your answer aloud. Solution: 3 x 3 x 3 x 3 = 3 4 3 raised to the fourth powerĮxample 3: 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.Įxample 2: 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. Look no further than the gem 561 1 W market leading power with an. Let us take another look at the table from above to see how exponents work. Looking for an efficient, high power yellow laser in a compact form factor Blog. Solution: 2 x 2 x 2 x 2 x 2 = 2 5 2 raised to the fifth power Read as two raised to the millionth powerĮxample 1: 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 exponent tells us how many times the base is used as a factor.įor 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 times for homework. The product of factors is also displayed in this table. In the table below, the number 2 is written as a factor repeatedly. What happens if you multiply two numbers in exponential form with the same base Consider the expression (23)(24). Learn about the rules of exponents with the following examples and interactive exercises.
