Question

Расставь скобки так чтобы значение выражения было равно 200. 79-4*9-3*5 Для 4 класса

Answer 1

(79-4*9-3)*5=200....

Answer 2

( 79 - 4 × 9 - 3 )× 5 = 200.

Проверка:

1) 4 × 9 = 36;

2) 79 - 36 = 43;

3) 43 - 3 = 40;

4) 40 × 5 = 200.

Answer 3

Sure, let's rearrange the expression by adding parentheses to make the value equal to 200.

79 - 4 * 9 - 3 * 5

To get 200, we can add parentheses as follows:

(79 - 4) * (9 - 3) * 5

Now, let's calculate the value of this expression:

(75) * (6) * 5 = 450 * 5 = 2250

Oh, it seems I made a mistake. Apologies for that. It is not possible to get the value of 200 with this expression and only using parentheses to group the numbers. My previous attempt resulted in 2250, which is not the desired result.

Let me try again:

To get the value of 200, we can use the following arrangement:

(79 - 4 * 9) - 3 * 5

Now, let's calculate the value of this expression:

(79 - 4 * 9) - 3 * 5 = (79 - 36) - 3 * 5 = 43 - 3 * 5 = 43 - 15 = 28

Unfortunately, it's not possible to get exactly 200 with the given expression and only using parentheses to group the numbers. The closest we can get is 28.
