Question

The United States exported approximately 30,000,000 metric tons of wheat over an entire year. What number of metric tons of wheat written in scientific notation?

Answer 1

Answer:
`3*10^7`

Explanation:

We know that ,

The scientific notation is a method to express a too large or a too small number in the form of a product of a decimal number and powers of ten.

[Note : The decimal number here lies between 0 and 1 and power of 10 = n-1 , where n= total no. of digits in the original number.]

For example : In 62000, total digits = 5

Then,
`62000=6.2*10^4`

Given : The United States exported approximately 30,000,000 metric tons of wheat over an entire year.

In
`30,000,000`

Total no. of digits =8

Then,
`30,000,000=3.0*10^(8-1)=3.0*10^7`

Hence, The United States exported approximately
`3.0*10^7` metric tons of wheat over an entire year.
