What are five examples of scientific notation?
Here are five examples:Multiply (4 x 104) and (7 x 105) First 4 x 7 = 28. Next add exponents, 4 + 5 = 9. Result is 28 x 109 ... Divide (6 x 105) by (4 x 104) 6/4 = 1.5. Subtract exponents 5 - 4 = 1. Answer 1.5 x 101 or 15.Multiply (4 x 10-7) and (3.25 x 109) 4 x 3.25 = 13. Add exponents = -7 + 9 = 2. Answer is 13 x 102 or 1300.

What is scientific notation?
Scientific notation is a form of presenting very large numbers or very small numbers in a simpler form. As we know, the whole numbers can be extended till infinity, but we cannot write such huge numbers on a piece of paper. Also, the numbers which are present at the millions place after the decimal needed to be represented in a simpler form. Thus, it is difficult to represent a few numbers in their expanded form. Hence, we use scientific notations. Also learn, Numbers In General Form.
