What is exponential notation?
Answers
The exponential notation helps to express a very large number in the form of a single number and 10 raised to the power of the respective exponent. The power of the exponent can be in two forms. It can be either positive or negative. Positive power denotes the number is large and negative power denotes the number is small.
Example: 1000 can be expressed as 10 X 10 X 10 = 103
1000= 103
In the exponential form 103:10 is regarded as base and 3 is regarded as an exponent
Other examples:
8= 23
16= 42
5000= 5 X 103
0.005= 5 X 0.001= 5 X 10-3
0.0345= 345 X 0.001= 345 X 10-3
Answer:
The exponential notation (sometimes called the "scientific" notation) greatly simplifies calculations, especially with very large and very small numbers. It uses positive and negative exponents to write multiples and submultiples of 10: Any number raised to the zeroth power equals one.
