What are Scientific notations?
Scientific notations is the way through which a very small or a very large number can be written in shorthand. In scientific notations when a number between 1 and 10s is multiplied by a power of 10.
For example, 6,500,000,000,000 can be written as 6.5e+12.
Given that there are 1.4×10⁸ pet fish and 9.4×10⁶ pet reptiles in the United States. Therefore, we can write the number as,
Number of pet fish = 1.4×10⁸ = 140,000,000
Number of pet reptiles = 9.4×10⁶ = 9,400,000
Now, the total number of pets can be written as,
Total number of pets = 140,000,000 + 9,400,000
= 149,400,000
= 1.494 × 10⁸
Hence, the total number of pets is 1.494 × 10⁸.
