Answer 1

Ответ:

Пошаговое объяснение:

121 х 5 + 12 х 5 =605 +60=665      стрелка к        5×(121 +12)=5*133=665

потому что это распределительный закон умножения

ас+вс=(а+в)с

241×2+36×2   нельзя провести стрелку ,потому что умножаются на разные числа ,на 2 и на 5 .

а если у вас опечатка,то тогда

( 241 + 36 )х 5=277*5=1385    и    стрелка   241×5+36×5=1205+180=1385

Answer 2

Two Methods of Multiplication

There are two main methods of multiplication: the traditional method and the lattice method.

1. Traditional Method: - In the traditional method, you multiply each digit of one number by each digit of the other number, starting from the rightmost digit and moving left. - You then add up the partial products to get the final product. - Here's an example using the numbers 241 and 36: ``` 241 x 36 ------- 1446 (241 x 6) 7220 (241 x 30) + 72360 (241 x 300) ------- 8676 (Final product) ```

2. Lattice Method: - The lattice method is an alternative method that uses a grid to organize the multiplication process. - Here's an example using the numbers 241 and 36: ``` 2 4 1 x 3 6 ---------------- 7 2 6 4 8 2 4 ---------------- 8 6 7 6 ```

Calculation

Let's calculate the expression: (241 + 36) x 5121 x 5 + 12 x 55 x (121 + 12) + 241 x 2 + 36 x 2.

Using the order of operations (PEMDAS/BODMAS), we start by evaluating the expressions within parentheses first.

1. (241 + 36) = 277 2. (121 + 12) = 133

Now we can substitute these values back into the original expression:

(277) x 5121 x 5 + 12 x 55 x (133) + 241 x 2 + 36 x 2

Next, we perform the multiplications:

1. 277 x 5121 x 5 = 7,106,205 2. 12 x 55 x 133 = 87,780 3. 241 x 2 = 482 4. 36 x 2 = 72

Finally, we add up all the results:

7,106,205 + 87,780 + 482 + 72 = 7,194,539

Therefore, the result of the expression (241 + 36) x 5121 x 5 + 12 x 55 x (121 + 12) + 241 x 2 + 36 x 2 is 7,194,539.

Please note that the calculation provided is based on the given expression and the order of operations. If there are any additional requirements or specific instructions, please let me know.
