1) 463 - (283 + 121) = 463 - 283 - 121 = 180 - 121 = 592*5*(3*6 - 16 + 1) = 10*(36 - 16 + 1) = 10*21 = 21059 < 2102) (823 + 102) - (321 + 271) = 925 - 592 = 333(31 - 29)*(76 - 67) + 34 = 2*9 + 34 = 18 + 34 = 52333 > 523) (850 - 841)*(723 - 715) = 9*8 = 72[(100 - 25) - (85 - 15)]*5 = [75 - 70]*5 = 5*5 = 2572 > 25
Если нужно, могу объяснить
1) 6!*(7! - 3!) = 720*(5040 - 6) = 720*5034 = 3624480
2) C(6, 10) = C(4, 10) = (10*9*8*7)/(1*2*3*4) = 10*3*7 = 210
3) p = 10/23*9/22 = 90/(23*22) = 45/(23*11) = 45/253
4) (a+b)^5 = a^5 + 5a^4*b + 10a^3*b^2 + 10a^2*b^3 + 5ab^4 + b^5
