The scientific notation of 11,900,000,000 is 1.19 × 10¹⁰.
Hence, Option (a) is the correct answer.
Scientific notation is a convenient way used in mathematical computations for expressing large numbers in an easier way when solving them with the use of decimal points multiplied by the power of 10 and which is raised to the power of their substituents after the decimal point.
From the given information, we will count how many decimal places we have after the first digit and raised it to the power of 10 with the remaining substituents after the decimal point.
i.e.
There are 10 substituents after the decimal point.
∴
11,900,000,000 can be written as 1.19 × 10¹⁰.
Therefore, we can conclude that the scientific notation of 11,900,000,000 is 1.19 × 10¹⁰.
