x=(15,72+3,25:0,01-2 x 7,3) ²
Y=(6,25:2,5 x(ori) 10²+20:0,01) x(ori) 0,5²

Answer 1

x=$(15,72+325-14,6)^{2}$
x=$(326,12)^{2}$

y=(250+2000)×0,25
y=2250×0,25
y=562,5

Answer 2

x = (15,72+325-14,6)^2
x = (340,72-14,6)^2
x = (326,12)^2

y = (2,5 * 100 + 2000) * 0,25 
y = (250+2000) * 0.25
y = 2250 * 0,25
y = 562,5
x+y = 106354,2544 + 562,5 = 106916,7544
x-y = 106354,2544 - 562,5 = 105791,7544
