Step-by-step explanation:
As Jean writes 75,000,000 in scientific notation as 75.
This is INCORRECT!
Here is the correct solution:
Given the number
75,000,000
Let us write the number 75000000 in scientific notation
We know that scientific notation is of the form [tex]a\times 10^b[/tex] where [tex]1\le a<10[/tex] and b is an integer.
Move the decimal point to the left to create a new number from 1 up to 10.
[tex]a=7.5000000[/tex]
Count the number of times you moved the decimal point
b = 7
so
[tex]=7.5000000\times 10^7[/tex]
Remove the trailing zeros
[tex]=7.5\times \:10^7[/tex]
Therefore, we conclude that:
75,000,000 in scientific notation: 7.5 × 10⁷
