Вычислите 1) (2/3) ^-2 - (1/9) ^-1 + (6/17) ^0*1/8-0,25^-2*6=

Вычислим значение выражения (2/3) ^ (-2) - (1/9) ^ (-1) + (6/17) ^0 * 1/8 - 0,25^ (-2) * 6.

1 / (2/3) ^2 - 1 / (1/9) + 1 * 1/8 - 1/0,25^ (2) * 6;

1 / (4/9) - 1 / (1/9) + 1/8 - 1 / (1/4) ^ (2) * 6;

9/4 - 9/1 + 1/8 - 1 / (1/16) * 6;

9/4 - 9/1 + 1/8 - 16 * 6;

9/4 - 9 + 1/8 - 16 * 6 = 9 * 2 / (4 * 2) - 9 + 1/8 - 10 * 6 - 6 * 6 = 18/8 + 1/8 - 9 - 60 - 36 = 19/8 - 9 - 60 - 36 = 19/8 - 96 - 9 = 19/8 - 105 = 2,375 - 105 = - 102,625;

В итоге получили, (2/3) ^ (-2) - (1/9) ^ (-1) + (6/17) ^0 * 1/8 - 0,25^ (-2) * 6 = - 102,625.

Ответ: - 102,625.
