The most general form is the decimal form. This comprises a string of digits using using 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. The digits are written so that the place value for each digit is ten times the place value of the digit to its right. Integer parts of numbers are separated from the fractional parts (values smaller than 1) by a decimal point, if required.
This form is the same as the expanded decimal form but with only the coefficients for the powers of 10.
The general form of a number in scientific notation is ax 10n, where a must be between 1 and 10, and nmust be an integer. (Thus, for example, these are not in scientific notation: 34 x 105; 4.8 x 100.5.).
It is using the scientific notation.
The general rule in formal writing (that which you do for school or work) is yes. All numbers that appear as two or fewer words should be written out.

Writing numbers in standard form is writing numbers regular. For example One million in standard form is 1,000,000.
The general form of a number in scientific notation is ax 10n, where a must be between 1 and 10, and nmust be an integer. (Thus, for example, these are not in scientific notation: 34 x 105; 4.8 x 100.5.).
It is using the scientific notation.
All prime numbers over 3 are either 6n - 1 or 6n + 1.
The general rule in formal writing (that which you do for school or work) is yes. All numbers that appear as two or fewer words should be written out.
a + i b, with a and b real numbers and i = sqrt(-1)
In general, the numbers form 21-99 are hyphenated; ninety-seven

Usually not.

Short word form is a way of writing numbers using digits and place value. It is a condensed way to represent a number by using numerals instead of writing out the full word form. For example, the short word form of the number 3,456 would be "3.456 x 10^3" or "3.456k" in scientific notation or "three thousand four hundred fifty-six" in standard form.
