Question

165×5×9÷5555×1234×78÷34×13

Answer 1

Запишем в виде дроби (все деления в знаменатель)

$\displaystyle \frac{165\cdot5\cdot9\cdot1234\cdot78\cdot13}{5555\cdot34}$

Заметим что $165=15\cdot11$ и $5555 = 505\cdot 11$, поэтому сократим на 11

$\displaystyle \frac{15\cdot5\cdot9\cdot1234\cdot78\cdot13}{505\cdot34}$

Можно еще сократить на 5 и на 2 (например разделив 78 на 2

$\displaystyle \frac{15\cdot9\cdot1234\cdot39\cdot13}{101\cdot17}$

Получающаяся дробь уже несократима, потому что снизу стоят два простых числа, а сверху на них ничто не делится (1234 = 2*617)

Ответ

$\displaystyle\frac{6497010}{1717}$

Answer 2

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). In your expression, there are no parentheses or exponents, so you can perform multiplication and division from left to right:

165 × 5 = 825 825 × 9 = 7425 7425 ÷ 5555 ≈ 1.3362 (rounded to four decimal places) 1.3362 × 1234 = 1648.0908 (rounded to four decimal places) 1648.0908 × 78 = 128243.4464 (rounded to four decimal places) 128243.4464 ÷ 34 = 3771.2675 (rounded to four decimal places) 3771.2675 × 13 ≈ 49005.4757 (rounded to four decimal places)

So, the result is approximately 49005.4757.
