Put it into standard form so you would have
27x10¯6 divided by 9x10¯6
Then you can divide the numbers so 27/9 = 3
Then to divide the powers you just take them away so - 6--6 = - 6 +6 = 0
Therefore the answer is just 3
The right answer is E because you have to multiply all those numbers and when you do you get 3,000
