Answer:729
Step-by-step explanation:X would be 7, so that would make 27^2, and 27^2 is 27x27, because it is 2 27s. Therefore, 27x27 equals 89, drag the 4 above the 2, and multiply the 7 with the top 2, and you mark out the 4 and put 1 over it. The answer for that would Ben 189, put down your denominator, and multiply the second 2 with 7 and the 2 above that 2, and then you get 540, and then you add the 189, 1 over that one, and plus it with 540, which would equal 729. Sorry if I made it sound confusing, I tried. Hope this helps, though!
