Answer 1

Ответ:

61.7 * 52.1 - 43.6 * ((119.62 + 218.48) / 13.8) =

3210.67 - 43.6 * (338.1 / 13.8) =

3210.67 - 43.6 * 24.45 =

3210.67 - 1051.52 =

2169.15


73.2 * 48.3 - 37.4 * ((166.02 + 219.38) / 16.4) =

3518.56 - 37.4 * ((166.02 + 219.38) / 16.4) =

3518.56 - 37.4 * (385.4 / 16.4) =

3518.56 - 37.4 * 23.55 =

3518.56 - 880.67 =

2637.89
