Answer 1

Ответ:

(81 - 79.3) * (24.04 - 22.68) * (1^2 + 1^2) =

1.7 * 1.36 * 2 =

3.672.

Пошаговое объяснение:

(55 + 8) + (8.82 / 25.3) - 3 + (1.5 / 9) * 4 =

63.82 / 25.3 - 3 + 0.1667 * 4 =

2.52 - 3 + 0.6667 =

-0.8147.

117.5 - 11/2 + (102^2 / 6 - 8/75) * 3 * 25 * 15 * 13 =

117.5 - 5.5 + (10404 / 6 - 8/75) * 3 * 25 * 15 * 13 =

117.5 - 5.5 + (1734 - 0.1067) * 3 * 25 * 15 * 13 =

117.5 - 5.5 + 25453.8933 =

25465.8933.

89.8 / 59 - 15 + 27 - 28 - 36 / 42 * (41 - 3.5) / 49 * 4 / 7 =

1.5237 - 15 + 27 - 28 - 0.8571 * 37.5 / 49 * 0.5714 =

1.5237 - 15 + 27 - 28 - 0.4329 * 0.7653 * 0.5714 =

1.5237 - 15 + 27 - 28 - 0.2462 =

-14.2015.

(73.6 - 72%) / 61 + 13 - (202 - 10) / 9 + 15 / 3 * 45 * 10 =

(73.6 - 0.72 * 73.6) / 61 + 13 - (192) / 9 + 750 =

(20.448 / 61) + 13 - 21.3333 + 750 =

0.3354 + 13 - 21.3333 + 750 =

742.0011.

(17 - 29) * (32.098 + 5.902) / (49 - 30^10) =

(-12) * 38 / (49 - 59049000000) =

-456 / (-59048999951) ≈ 7.71 * 10^-9.

Answer 2

Давайте рассчитаем каждое из указанных выражений:

1. $55 + \frac{8}{8.82} : 25.3 - 3 + \frac{1.5}{9}$: $= 55 + 0.907 \div 25.3 - 3 + 0.167$ $≈ 55 + 0.036 - 3 + 0.167$ $≈ 52.203$

2. $117.5 - \frac{11}{2} + \left(\frac{102^2}{6} - \frac{8}{75}\right) \div 3 \times 25 \div 15 \div 13$: $= 117.5 - 5.5 + \left(\frac{102 \times 102}{6} - \frac{8}{75}\right) \div 3 \times 25 \div 15 \div 13$ $≈ 117.5 - 5.5 + 1767.08 - 0.10667$ $≈ 1879.97333$

3. $89.8 \div 59 - 15 + 27 \div 28 - 36 \div 42 - \frac{41 - 3.5}{49 \div 4 \div 7}$: $= 1.52034 - 15 + 0.96429 - 0.85714 - 0.0619$ $≈ -13.43359$

4. $\frac{73.6 - 72\%}{61} + 13 - (202 - 10) \div 9 \times 15 \div 3 \times 45 \div 10$: $= \frac{73.6 - 0.72 \times 73.6}{61} + 13 - \frac{192}{9} \times 15 \div 3 \times 45 \div 10$ $= 1.188524 + 13 - 21.333333 \times 15 \div 3 \times 45 \div 10$ $= 1.188524 + 13 - 319.99999$ $≈ -305.811466$

5. $\frac{17 - 29}{(32.098 + 5.902) / (49 - 30 \times 10)}$: $= \frac{-12}{(38.00) / (19)}$ $= \frac{-12}{2}$ $= -6$

6. $\frac{(81 - 79.3)}{(24.04 - 22.68)} \times (1^2 + 1^2)$: $= \frac{1.7}{1.36} \times 2$ $≈ 2.5$
