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.
Fortunately there are websites dedicated to mathematics that provide guides and tips. The website LearnZillion provides a video tutorial on how to use whole number exponents to denote powers.
You can use any number - rational or otherwise - as an exponent.
Because
Numbers expressed using exponents are called powers. When writing a number expressed as an exponent, the number is called the base.

One use is shorthand for large numbers, eg the mass of the earth is 5960000000000000000000000 kg , which can be expressed as: 5.96 * 1024 kg there are also rules for multiplying / dividing exponential numbers
Exponents are used to replace repeated factors. Prime numbers won't use exponents because they don't have repeated factors. To express the prime factorization of a particular composite number using exponents, just count. 2 x 2 x 2 x 3 x 3 = 72 23 x 32 = 72
For convenience. Sometimes larger numbers have a lot of repeated factors.
Formulae is one of the plurals for formula. There are many formulas in mathematics. For example, the formula for the area of a rectangle is length x width. You use it by plugging in numbers. If the length is 7 units and the width is 5 units, the area is 35 square units
Scientific notation is the use of exponents to indicate large numbers; for example, the number 25,000,000 can also be written in the form 2.5 x 107
The laws of exponents work the same with rational exponents, the difference being they use fractions not integers.
42 or 24 If you want to be fancy you can use exponents less than one 2561/2 or 40961/3
