When inputting answers, we're going to use the palette over here on the left. So for the F of S, it's going to be 5S when I come to the left and use the power to power key square. When I arrow over to get off of that square plus 4S. For the next one, I'm going to have five times the quantity of 2A squared. SO20A over here to the palette power to power the square, arrow off the square plus 8A. The last 1F of three which we found a minute ago which was 5757 -, 9, so 48. Hope this helps.
