what is the Scientific Notation?

Answer 1

A method of writing or displaying numbers in terms of a decimal number between 1 and 10 multiplied by a power of 10. The scientific notation of 10,492, for example, is 1.0492 × 104.

Answer 2

Scientific notation is a notation for writing numbers that is often used by scientists and mathematicians to make it easier to write large and small numbers. A number that is written in scientific notation has several properties that make it very useful to scientists.

In scientific notation, numbers are written using powers of ten in the form a×10b where b is an integer exponent and the coefficient a is any real number, called the significand or mantissa (using "mantissa" may cause confusion as it can also refer to the fractional part of the common logarithm).

In normalized form, a is chosen such that 1 ≤ a < 10. Following this rule allows easy comparison of two positive numbers as the one with the larger power of ten must be larger. In normalized form, the exponent b gives the number's order of magnitude. It is implicitly assumed that scientific notation should always be normalized except during calculations or when an unnormalized form is desired (e.g. engineering notation

Answer 3

Scientific Notation is a way to show really big or really small numbers, using powers of ten.

Take the number 12,458.

For numbers like these, you have to multiply a decimal or whole inbetween one and ten, but it can't be one or ten.

So, that number would be 1.2458.

Next, multiply by a power of ten. In this case, raise ten the the fourth power.

So it would be...

1.2458*10^4=12,458!

I forgot how to do the small numbers.

Answer 4

calculators use it because they can't use superscript for exponents. So, they say "e" for exponent: 10e5 is 10 to the fifth power.

Answer 5

x10 to whatever
