а)(1142600-890778):74+309*708=
б)13²+(52-49)³=

Answer 1

а) (1142600 - 890778) / 74 + 309 * 708 = 251822/74 + 218772 = 3403 +218772      
=222175
б)  13^2 + (52 - 49) ^3 = 13^2  + 3^3= 169 + 27 = 196

Answer 2

$1)(1142600-890778):74+309*708= \\ =3403+218772=222175$

$2)13 ^{2} +(52-49) ^{3} =169+3 ^{3} =169+27=196$
