First we identify the confessions of this craziness, echoes one vehicles minus eight and say calls 36. Next we substitute A. D. Can see with their values into this formula. Denominators to the numerator is eight plus some miners the square root of miners eight squared miners four times a long time 36 which equals 8000 miners square road. On minus 80 over to which is four plus miners two times the square root of minus five. Here we need to use I, which is the unit of the imaginary number and I echoes the square root of minus one. Show the first solution is four miners to times square root five I. And the second solution is for plus to times square root five. Art
