Therefore the value in scientific notation is: 1.05 x 10 14 x 10 12 -now the decimal must be moved two places over and the exponent is raised by 2. For each place we move the decimal over the exponent will be raised 1 power of ten.ģ0.x106 = 3.0 x 107 in scientific notation. We then must move the decimal point over to the left until the coefficient is between 1 and 10. While the value is correct it is not correctly written in scientific notation, since the coefficient is not between 1 and 10. What happens if the coefficient is more than 10 when using scientific notation?Įxample 2: (5 x 10 3) (6x 103) = 30. Rules for Multiplication in Scientific Notation: In the number 1.23 x 1011 the number 11 is referred to as the exponent or power of ten. The base number 10 is always written in exponent form. It must always be 10 in scientific notation. Multiplying or dividing by these powers simply requires us to move the decimal place of the number weâre multiplying or dividing. It must be greater than or equal to 1 and less than 10. A power of 10 is a number that can be written as 10 raised to a power or exponent. The first number 1.23 is called the coefficient. The number 123,000,000,000 in scientific notation is written as : Scientific Notation is based on powers of the base number 10.

This leads to a convenient way to denote very large or very small numbers that include other digits than 10, such as 1.3*10 4 to denote 13,000. You can also denote small numbers as multiples of 1/10 as powers of 10, such as 0.0001 = 10 −4. You can denote large numbers that are multiples of 10 as powers, such as 1,000,000 = 10 6. Likewise, 2.5*10 −3 would display as 2.5E−3 on the calculator. In other words, on a calculator 9.2*10 7 might be displayed as 9.2E7. Most hand-held calculators denote raising to a power of 10 with an E (meaning exponential). The table shows how other larger numbers can be written. You can also denote number with other digits in powers of 10, such asįollowing the convention for writing numbers to the power of 10, you should change 25*10 −4 to 2.5*10*10 −4 = 2.5*10 −3. For example 100 is equal to 10 times 10 and we can write this as 102. This is also called the scientific notation of an exponential number. The usual convention in writing a number times a power of 10 is to reduce the digits in the first number to a value between 1 and 10.

You could rewrite that number as 92*1000000 miles, which can be designated as 92*10 6 miles. For example, the distance from the Earth to the Sun is approximately 92,000,000 miles. Since most large numbers have other digits involved, you can break the number into parts. Other large and small numbers can be written as powers of 10.

Another example is 0.0001 = 10 −4, since there are four places to the right of the decimal point. Example: 3 × 104 30,000 How to multiply by powers of 10 Examples: Multiplying by Powers of Ten Notice that 10n in expanded form is 1 followed by n zeros. The easy way to figure it out is to count the number of placed to the right of the decimal point. Numbers smaller than 1 can be written in powers of 10 by using a negative exponent, which means the reciprocal of the number. This is very convenient, because all you have to do is to add the number of zeros and use that as the exponent. Large multiples of 10 numbers can be written in terms of powers of 10.
