Exponents are negative numbers. This is used in math a lot.

Very very small numbers as for example 0.00000078 = 7.8*10^-7 in scientific notation

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.

Yes, except for zero. Numbers larger than 1 have positive exponents, and numbers between 0 and 1 have negative exponents. Negative numbers would just have a '-' in front.

Only if the numbers to be converted into scientific notation are the same otherwise the exponents can vary according to the size the numbers.

Move the decimal to the right for positive exponents, and the left for negative exponents. 1.23 x 10^3 = 1230 1.23 x 10^-3 = 0.00123

In scientific notation, you use exponents divisible by 3. For example, 12,750 is 12.75 Ã— 10Â³ instead of 1.275 Ã— 10â´.

It is: 9.3*10^7 in scientific notation

When the absolute value of the number being expressed is less than 1: that is, the number lies between -1 and +1.

yes its really important
