Scientific Notation

9 billion written in scientific notation is: 9 x 10^9

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.
The practical applications are representing large and small numbers is a simple way.

It is: 5*10^-3 = 5/1000 or 0.005

120,000 = 1.2e5 or 1.2 x 10^5

It is: 1.66*10^7

8,000 = 8.0 × 10^3 or 8.0E3

2,200,000 = 2.2 x 10^6

1.5 x 10^-3 is scientific notation.

It is: 4.5*10^-3

7.5 x 10^4

7.8 x 10^7

It is: 2.75*10^6

The form for scientific notation is a*10b where 1 <= a < 10, and b is an integer (positive or negative).

2.5 x 10^13

560,000 in Scientific Notation = 5.6 x 10^5

0.0304

2400 = 2.4 x 10^3

0.0024 = 2.4 x 10^-3

Move the decimal to the left, positive exponent. Move the decimal to the right, negative exponent.

It is: 5.08*10^8 in scientific notation and the exponent of 10 is 8

The exponent of 10 tells you how many places to move the decimal point to the left if it is minus or to the right if it is plus.

It is: 2,800,000,000 or as 2.8*10^9 in scientific notation

4.7338 x 10^6

6.72 x 10^-1

Yes, it would look like this: 0.2 x 10^5 or 0.2E5

19 trillion can be written in scientific notation as 1.9 x 10^13.

It is: 4.32*10^8
