Answer: 8.70064 × [tex]10^{7}[/tex]
Step-by-step explanation: To write a number in scientific notation, first write a decimal point in the number so that there is only 1 digit to the left of the decimal point.
So here, we can write 87,006,400 as 8.7006400 and notice that there is only 1 digit to the left of the decimal point.
Next, we count the number of places the decimal point would need to move to get back the original number which is 87,006,400. Since we would need to move the decimal point 7 places to the left, we have an exponent of 7.
Scientific notation is always expressed as 10 to a power so we can write 87,006,400 as 8.70064 × [tex]10^{7}[/tex].
We can drop the two zeroes at the end since they don't have any value.
