It is nearly true. The exception is when convention requires one or more zeros to be appended after the decimal point. One example of this is when relatively small money values are being shown. The unit price when 2 items cost GBP3 would be shown as GBP1.50, not GBP 1.5
That is correct.
Since the decimal place is between the leading nonzero digit and the adjacent digit on the right, there is no need to shift the decimal point. Therefore, 1.07 in scientific notation is: 1.07 * 100
727000 in scientific notation is written as 7.27 x 10^5. In scientific notation, the number is expressed as a decimal between 1 and 10, multiplied by a power of 10. In this case, the decimal is 7.27, and it is multiplied by 10 raised to the power of 5.
Place the decimal so the number is between 1 and 10. Then count back however many places you moved the decimal.9.210 × 103
You will have a negative decimal. For example, -754 in scientific notation is -7.54*10^2.
True
That is correct.
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.
Well, adding x10 is scientific notation. Example:456-4.56x102. this is because there are two numbers before the decimal. another example:14945-1.4945x104. if you do not get it, I'm sorry. This is the best i can explain
What is the difference between 6500. and 6500? The first one would be considered to have a terminal decimal. This means that instead of simply writing the number as it is, a decimal is added to the end to represent significant figures (terminal decimals are most commonly used in scientific notation). Therefore, when 6500 would only be considered as to having 2 significant figures, 6500. has 4 significant figures.

Since a decimal point is not located between the leading nonzero digit and the adjacent digit, the term is not in scientific notation. So to make that term in scientific notation, shift 2 more decimal places to obtain 4.25 x 107.
All digits between the first non-zero digit and the last non-zero digits are significant. Some would argue that trailing 0s are significant since they are an indication of the precision of the number.
Since the decimal place occurs between the leading nonzero coefficient and the adjacent digit 7, there is no need to move a decimal place either left or right. Therefore, we have 2.7 x 100 in scientific notation.
