а) (5³ + 13²) : 21First calculate 5³ (5 cubed) = 5 5 5 = 125Then calculate 13² (13 squared) = 13 * 13 = 169Add 125 and 169 = 294Finally, divide 294 by 21 = 14
So, (5³ + 13²) : 21 = 14
б) 180 94 - 47700:45 + 4946First calculate 180 94 = 16920Then subtract 47700 divided by 45 (47700 : 45 = 1060)Add the result of the subtraction and 4946So, 16920 - 1060 + 4946 = 20420
Therefore, 180 * 94 - 47700:45 + 4946 = 20420
