Answer 1

Ответ:

Пошаговое объяснение:

(92578+3206)*800-(50010-3215)*90=72 415 650

1)  92 578*3 206=95 784

2) 95 784 *800= 76 627 200

3) 50 010-3215 = 46 795

4) 46 795* 90= 4 211 550

5) 76 627 200 -4 211 550 = 72 415 650

(42071-970*40)*7000-48000:80+256740*600= 176 940 400    

1)970*40=38 800

2)42 071-38 800=3 271

3)3 271*7000=22 897 000

4)48 000:80=600

5)256 740*600=154 044 000

6)22 897 000-600=22 896 400

7)154 044 000+22 896 400=176 940 400    

Answer 2

Let's solve these mathematical expressions step by step:

а) (92578 + 3206) * 800 - (50010 - 3215.90)

First, calculate the values inside the parentheses: 92578 + 3206 = 95784 50010 - 3215.90 = 46794.1

Now, substitute these values back into the expression:

95784 * 800 - 46794.1

Now, perform the multiplication and subtraction:

76627200 - 46794.1 = 76580405.9

So, the result of the expression (92578 + 3206) * 800 - (50010 - 3215.90) is approximately 76,580,405.9.

б) (42071 - 970.40) * 7000 - 48000 / 80 + 256740.600

First, calculate the values inside the parentheses and the division:

42071 - 970.40 = 41100.60 48000 / 80 = 600

Now, substitute these values back into the expression:

(41100.60) * 7000 - 600 + 256740.600

Now, perform the multiplication and addition:

287704200 - 600 + 256740.600 = 287960340.6

So, the result of the expression (42071 - 970.40) * 7000 - 48000 / 80 + 256740.600 is approximately 287,960,340.6.
