Answer: [tex]3\times10^7[/tex]
Step-by-step 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, [tex]62000=6.2\times10^4[/tex]
Given : The United States exported approximately 30,000,000 metric tons of wheat over an entire year.
In [tex]30,000,000[/tex]
Total no. of digits =8
Then, [tex]30,000,000=3.0\times10^{8-1}=3.0\times10^7[/tex]
Hence, The United States exported approximately [tex]3.0\times10^7[/tex] metric tons of wheat over an entire year.
