Question

Вычислите пример:16*25=4*(4*25)=4*100=400 82*2 36*25 25*32 28*25 16*125 64*125 75*12 75*44

Answer 1

82 * 2 = (41 * 2) * 2 = 41 * 4 = 164
36 * 25 = (6 * 6) * (5 * 5) = 30 * 30 = 900
25 * 32 = (5 * 5) * (16 * 2) = 80 * 10 = 800
28 * 25 = (7 * 4) * (5 * 5) = 35 * 20 = 70 * 10 = 700

16 * 125 = (4 * 4) * (5 * 25) = 20 * 100 = 2000
64 * 125 = (8 * 8) * (5 * 25) = 40 * (25 * 4 * 2) = 40 * (100 * 2) = 40 * 200 = 8000
75 * 12 = (5 * 15) * (3 * 4) = 20 * 45 = 10 * 90 = 900
75 * 44 = (25 * 3) * (4 * 11) = 100 * 33 = 3300

Answer 2

Конечно, давайте посчитаем этот пример по частям.

\[ 16 \times 25 = 400 \]

\[ 4 \times (4 \times 25) = 4 \times 100 = 400 \]

\[ 82 \times 2 = 164 \]

\[ 36 \times 25 = 900 \]

\[ 25 \times 32 = 800 \]

\[ 28 \times 25 = 700 \]

\[ 16 \times 125 = 2000 \]

\[ 64 \times 125 = 8000 \]

\[ 75 \times 12 = 900 \]

\[ 75 \times 44 = 3300 \]

Теперь сложим все эти значения вместе:

\[ 400 + 400 + 164 + 900 + 800 + 700 + 2000 + 8000 + 900 + 3300 = 18064 \]

Итак, результат выражения \(16 \times 25 = 4 \times (4 \times 25) = 4 \times 100 = 400 + 82 \times 2 + 36 \times 25 + 25 \times 32 + 28 \times 25 + 16 \times 125 + 64 \times 125 + 75 \times 12 + 75 \times 44\) равен 18064.
