How is a number converted to scientific notation?

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 to scientific notation:

Answer 2

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 to scientific notation:

· If the number has no decimal point, then add one at the end.

· Then move the decimal point to just after the first digit while counting the number of places you have moved it.

· The new number, formed after moving the decimal point is a.

· The number of places to the left that the decimal point was moved is b. If it was moved to the right, then b is negative.

For example:

23045.06 becomes 2.304506*104

0.00023004 becomes 2.3004*10-4

To convert a number in scientific notation to normal form:

Answer 3

Scientific notation is a way of representing numbers, usually very large or very small, in the form a*10^b 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 to scientific notation: · If the number has no decimal point, then add one at the end. · Then move the decimal point to just after the first digit while counting the number of places you have moved it. · The mantissa of the new number, formed after moving the decimal point is a. · If the original number is negative, then so is a. · The number of places to the left that the decimal point was moved is b. If it was moved to the right, then bis negative.
