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
How do you change a number from scientific notation to decimal notation?
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
How will you know the exponent of scientific notation is negative or positive?
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.
What is 7.1 x 10 to the 4 power in standard form?
71000 Move the decimal to the right four spaces (the same number as the exponent).
What number is represented by 2.3 x 10-3?
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.
