Scientific notation is a way to write very large or very small numbers using exponents. For example 2000 is 2x103 . We can do the same thing with negative exponents and write very small numbers like 1/2000 which is 2x10-3 . So one real life use of exponents in in scientific notation.
Base, power, answer
First you separate it into prime factors (start looking for small factors, such as 2, 3, 5). Then, you combine the factors with exponents.
You give them exponents. For example 5 becomes a power when it is 5 to the 3rd power (5^3).

You do not write numbers in exponent for in words.

It makes complicated equations and long numbers easier to write. It also gets you in hot chicks pants.
Usually not.
You give them exponents. For example 5 becomes a power when it is 5 to the 3rd power (5^3).
No prime power exists since there are no duplicate prime numbers in the prime factorization.

As a product of its prime factors in exponents: 22*3*52 = 300
Scientific notation is a method of writing numbers with exponents, to avoid having to write all the zeroes which may be present either in very large numbers or very small numbers. For example, a trillion, which is 1,000,000,000,000 can be written as 1012 and 3 billionths, which is .000000003 can be written as 3 x 10-9.
