Scientific notation is the way that scientists easily handle very large numbers or very small numbers. Scientific notation is written by writting a decimal number between 1 and 10 together with an exponent of 10.

Given


First, using distributive property of numbers, seperate the decimal numbers and the exponents of 10, we have


Because, scientific notation requires that the decimal number part be a number between 1 and 10, we move the decimal point 1 place foward and subtract 1 from the exponent of 10.

Therefore,
in standard notation is

20000 as first it increases by 2500 then by 5000 so next it will increase by 10000
