Why can an exponent be a fraction or decimal?
Why not? An exponent is just like any other number.
What is 0.0000972 in scientific notation?
9.72 x 10-5 You put the decimal behind the first digit. Then count the number of places the decimal moved from its original position. This number becomes the exponent of the 10. If you move the decimal to the left, it is a positive number for the exponent. To the right, it is a negative exponent.
HOW DO convert scientific notation to decimalnumbers?
The exponent tells you how many spaces to move the decimal, remember to add zeros as needed. If the exponent is negative make it a decimal number less than one by moving the decimal to the left. If the exponent is positive make the decimal number greater than one by moving the decimal to the right.
How do you put a number into scientific notation?
Count the number of spaces to move the decimal until the number has one (non-zero) digit to the left of the decimal. If the original number is larger than 1, then the exponent is positive, if smaller than 1 the exponent is negative. The exponent is that number of spaces that the decimal was moved. EX: 5100 = 5.1 x 102 and 0.00064 = 6.4 x 10-4
How do you put things out of scientific notation?
If the exponent is positive, move the decimal to the right the same number of spaces as the number of the exponent. If the exponent is negative, move the decimal to the left the same number of spaces as the number of the exponent.Examples:2.5 x 103 is 2500 in standard notation. (Move the decimal to the right 3 spaces.)4.9 x 10-5 is 0.000049 in standard notation. (Move the decimal to the left 5 spaces.)

How do you convert scientific notation to decimal notation?
If the number in sci. notation has a positive exponent, move the decimal to the right the same number of spaces as the exponent's number. For example: 5.78 x 103 = 5780 If the exponent is negative, move the decimal to the left the same number of spaces as the exponent's number. For example: 2.945 x 10-5 = 0.00002945

Do you express scientific notation?
Scientific Notation is expressed by using a number, using an exponent as a number (usually a decimal) multiplied by a 10, and an exponent (the number on the exponent is the number of zeros the number has).Example: 120,000,000 in scientific notation is 1.2 X 107
How do you change powers in scientific notation?
To change a number from standard to scientific notation, move the decimal point to create a number between 1 and 10. Count the number of places you moved the decimal point to get the power of 10. If you moved it to the left, the exponent is positive, and if you moved it to the right, the exponent is negative.
What is the exponent on the decimal number 0.1?
10-1 = 1/10 = 0.1
What is 0.0000105 in scientific notation?
A number in scientific notation should have one number before the decimal place then two after. You move the decimal so this is true, then the number of places you moved the decimal will be the exponent. If you move the decimal to the right your exponent will be negative, if you move it to the left it will be positive. In this case you would move the decimal 5 places so you have 1.05x10^-5.
What are the rules of changing number to Scientific notation?
Move the decimal until there is one nonzero digit to the left of the decimal counting the spaces that you move the decimal. That number of spaces becomes the exponent of 10. The exponent is positive if the original number was greater than 10, but is negative if the original number is less than one.
What is 386 000 km in scientific notation?
3.86 x 105 Scientific notation is useful to get rid of seeing the zeros in a number. Count how many places you need to move your decimal place to have the last non zero number in the ones place and the rest of the numbers to the right of the decimal. The number of movements will be the exponent. When you are moving the decimal place to the left your exponent will be positive, when moving the decimal right, your exponent will be negative.
