Answer 1

Ответ:

1)59*101=5959

2)5959-3645=2314

3)400322 : 2314=173

4)173+827=1000

1128 + 266832 ÷ (8460 − 302 × 27) = 2000

1) 302 × 27 = 8154

2) 8460 − 8154 = 306

3) 266832 ÷ 306 = 872

4) 1128 + 872 = 2000

Answer 3

Let's solve these mathematical expressions step by step:

1. $400 \cdot 322 : (59 \cdot 101 - 3645) + 827$

First, calculate what's inside the parentheses:

$59 \cdot 101 = 5,959$

Now, subtract 3645 from that:

$5,959 - 3645 = 2,314$

Now, the expression becomes:

$400 \cdot 322 : 2,314 + 827$

Now, multiply 400 by 322:

$400 \cdot 322 = 128,800$

Now, the expression becomes:

$128,800 : 2,314 + 827$

Now, divide 128,800 by 2,314:

$128,800 / 2,314 = 55.68$

Finally, add 827 to 55.68:

$55.68 + 827 = 882.68$

So, the result of the first expression is approximately 882.68.

2. $1128 + 266 \cdot 832 : (8460 - 30227)$

First, calculate what's inside the parentheses:

$8460 - 30227 = -21,767$

Now, the expression becomes:

$1128 + 266 \cdot 832 : -21,767$

Now, multiply 266 by 832:

$266 \cdot 832 = 221,312$

Now, the expression becomes:

$1128 + 221,312 : -21,767$

Now, divide 221,312 by -21,767:

$221,312 / -21,767 ≈ -10.15$

Finally, add 1128 to -10.15:

$1128 - 10.15 ≈ 1117.85$

So, the result of the second expression is approximately 1117.85.
