It is the power of negative 6.
It the power is d, where d is a signed integer, the decimal point moves d place to the right.
10^6
75 is an integer, not a fraction. As a decimal it is 75, exactly as in the question.
14 as a decimal is 14.0 14 as a fraction is 14/1
In the SI or metric system d stands for deci- which means 1/10. E.g. 1 decimeter = 0.1 meter
The power is -12 or a trillionth.
10 to the power of -12
It is the power of negative 6.
It the power is d, where d is a signed integer, the decimal point moves d place to the right.
A proper fraction in which the denominator is a power of 10.
10-2
10^6
Some common tools used to represent decimal values include: Decimal notation: This is the most common and widely used way to represent decimal values, using a decimal point followed by digits from 0-9. Fraction notation: Decimal values can also be represented as fractions, where the numerator is the decimal value and the denominator is a power of 10. Scientific notation: Decimal values can be represented in scientific notation, where a number between 1 and 10 is multiplied by a power of 10. This is particularly useful for very large or very small decimal values.
They may be ellipsis which represent repeating digits.
As we look at 1.98381100 here, we see it has only one digit to the left of the decimal. That is the basis for scientific notation. That and representing the shifting of the decimal point to get a character string with that one digit to the left of the decimal. When we shift the decimal to write a number in scientific notation, we use a power of ten to designate the decimal shift needed to get that character string with the single digit to the left of the decimal. Here we don't need a decimal shift, so we don't need a power of ten. If we were going to write it with a power of ten, it would look like this: 1.98381100 x 100 In this expression, we see 100 in there, and we know any number to the zero power is one. As 100 equals one, why do we need to write it? The answer is that we don't. The number you wished to represent in scientific notation is already that way. The power of ten is only needed if there anything but one digit left of the decimal place in the number under consideration.
