Answer:
8.86 x 10^8
Step-by-step explanation:
Scientific notation means that you represent the standard form of a number like this:
number less than ten x 10 to the ___ power
In standard form, the decimal point is at the end of 886,000,000.
You have to move the decimal point to the left until it creates a number less than 10, but greater than 1:
8.86,000,000
You count how many decimal places you moved it. In this case, it is 8.
So your answer becomes 8.86 x 10^8
You have to add 10 last.
divide 75÷8 and then add 10
