If the exponent is positive, you move the decimal point to the right, the specified number of digits. For a negative exponent, you move it to the left. In either case, you fill out missing digits with zero. Examples (using "^" for power):3.448 x 10^1 = 34.48
5 x 10^6 = 5000000 (note the implied decimal point to the right of the number)
3 x 10^-3 = 0.003
Move the decimal point the number of digits equal to the power of 10. if it is positive, move to the right; if negative move to the left.
If the exponent is negative then move the decimal point to the left.

How do you change a number in decimal notation to scientific notation?
times by the little number like .420 is 80
Rules in converting scientific notation to decimal notation?
to convert scientific notation to decimal you count the number of spaces up to the last digit then put the decimal point then put x10 to the power of if how many places you move the decimal point.................................
Is 1.58 the same as 1.588235294 in scientific notation?
No, scientific notation is when you express a number as a multiple of a power of ten. 1.58 would be rounding the number not changing it to scientific notation. To change 1.588235294 to scientific notation, you multiply 1.588235294 by a multiple of 10 to move the decimal point to the right until there is one number to the right of the decimal point.. So 1.588235294 * 100000000 = 158823529.4 Then you express 100000000 as an exponent. 100000000 = 10^7. BUT!!! Because to change 158823529.4 back into 1.588235294, you would have to divide it by 10^7, you have to change it to a negative exponent so 10^-7. The final answer is 158823529.4*10^-7 which is the same as 158823529.4/10^7 or 158823529.4/100000000.
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
Why are extremely large and small numbers expressed in scientific notation than decimal notation?
Large Number & Small Number are Difficult to Write and Read,So a Method For Writing and Reading them More Easily This Calle Scientific notation ,To Computation make easy! :)))

What is 80.007.00 in scientific notation?
It is not possible to convert a number with 2 decimal points into scientific notation.
What is -6.65 in scientific notation?
Since the entered decimal number -6.65 already has only one number to the left of the decimal point, the number is already in scientific notation format.
What is 7.27 in scientific notation?
7.27 already has only one number to the left of the decimal point; the number is already in scientific notation.
How do you convert 3.744000 to a scientific notation?
3.744000 is scientific notation is 3.744 x 100. This is because the decimal is already placed where it would be after converting the number to scientific notation. However, if you wanted to convert 3744000.0 to scientific notation, you would have to move the decimal left six places. This number, in scientific notation, is 3.744 x 106.
What is the difference between scientific notation and decimal number?
Scientific notation involves representing each digit in the number as a power of ten. In a decimal number, you just write the digits in order with a decimal point in the appropriate place.
Can you have a whole number in scientific notation?
Yes. A whole number is any positive number including zero. Let's say you want to use the whole number 47. The scientific notation for 47 is 4.7 times 101. You can put any number into scientific notation except fractions. You would have to change the fraction to a decimal (if possible) before you could put it into scientific notation.
Why the decimals are also used in scientific notation?
In scientific notation, the coefficient (number before the base 10) is written such that there is only one digit before the decimal point, and that digit can be 1 to 9. After that, the rest of the number is written after the decimal point, and there is no limit to the number of digits after the decimal point. The exponent on the 10 indicates how many places to move the decimal in order to change the number to standard form. Conversely, when going from standard form to scientific notation, the exponent indicates the number of places to move the decimal to change the number from standard form to scientific notation.Examples:1.48762 x 105 = 148762 in standard form7.593 x 10-3 = 0.007593 in standard form39732 = 3.9732 x 104 in scientific notation0.046 = 4.6 x 10-2 in scientific notation

What is the standard number for 0.0009812 in scientific notation?
9.812x10-4 is the scientific notation. The decimal moves four times to the right.
How do you change a number to a scientific notations?
You simply take the number of digits less one as the power, convert the number to a decimal between 0 and 10 and then note this decimal x 10 to the power calculated previously. e.g. 1,000,000 in scientific notation is 1.0 x 106 123,000,000 in scientific notation is 1.23 x 108
