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
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 = 34.485 x 10^6 = 5000000 (note the implied decimal point to the right of the number)3 x 10^-3 = 0.003
The smaller number at the top right of the ten may or may not have a negative sign in front of it: like 6.2 x 102 or 6.2 x 10-2. If the little number is positive, the decimal in the first number will move to the right. If the exponent is negative, the decimal in the first number will move to the left.
71000 Move the decimal to the right four spaces (the same number as the exponent).
The answer is 0.0023The interpretation is determined by the exponent of the 10.If the exponent is negative, then you move the decimal that # of places to the left.If the exponent is positive, then you move the decimal that # of places to the right.In your example, I moved the decimal three places to the right, and that gives me 0.0023.In the example, "7.53 x 10^4", I would move the decimal place four places to the right. Therefore, the number represented is 75,300Think of it simply like this if you don't get it. What is 5 x 10^1? You can better write this as 5 x 10 because 10 to the 1 power is just 10. It is easy, right? 5 x 10 = 50Well, 5 x 10^1 just means that you moved the decimal place over one place to the right. Isn't that what we did? 5.0 with the decimal place moved over to the right one place is 50.
The answer depends on why you move the decimal point to the right. In the context of scientific notation, you increase the exponent by the number of place that the decimal place is moved.
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.)
2400 = 2.4 x 10^3 0.0024 = 2.4 x 10^-3 Move the decimal to the left, positive exponent. Move the decimal to the right, negative exponent.
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.
7.23x10^-4. Move the decimal place to the right. The number of times you move the decimal is the same number as the exponent.
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

The exponent indicates how many spaces to move the decimal point to the right (+) or to the left (-) when expanded.
No, if you shift the decimal point to the left, the exponent of base 10 is positive. The exponent of base 10 is negative if you shift the decimal point to the right.
The exponent of 10 tells you how many places to move the decimal point to the left if it is minus or to the right if it is plus.
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.
If the exponent is b, then you move the decimal point b places to the right - inserting zeros if necessary.
