How do you write standard notation in a decimal?

Answer 1

Scientific notation is a way of representing numbers, usually very large or very small, in the form a*10b where 1 <= |a| < 10 is a decimal number and b is an integer (negative or positive). a is called the mantissa and b is called the exponent. To convert a number in scientific notation to normal form:

• If b is positive, move the decimal point b places to the right in the number a – adding 0s at the end of the number, if required.
• If b is negative, move the decimal point b places to the left in the number a – adding 0s immediately after the decimal point, if required.
• The final expression has the same sign (+ or -) as a in the scientific form.

For example: 4.56*105 = 456000. -4.56*105 = -456000. 4.56*10-5 = 0.0000456
