Detailed Solution

It is given 1 100000000  .
In exponents the standard form of a number is written as a decimal number between and, multiplied by power of 10.
Representing equation in the exponent form
⇒ 1 100000000 = 1 10 8  
Using the exponent law, 1 a m = a −m   ⇒ 1 100000000 = 10 −8  
Therefore, the standard form of 1 100000000   is 1.0× 10 −8  .
Hence option (4) is correct.
