Answer 1

Пошаговое объяснение:

900:10+20×80=90+1600=1690

460:10:23+800:40×7= 2+140=142

54×68:18+5016:24=204+209=413

4900:14(62×205-12360)=4900:14(12710-12360)= =350×350=122500

Answer 2

Let's solve each expression step by step:

1. 900:10 + 20×80 First, perform the multiplication: 20×80 = 1600 Then, divide 900 by 10: 900/10 = 90 Finally, add the results: 90 + 1600 = 1690

2. 460:10:23 + 800:40×7 First, perform the divisions from left to right: 460/10 = 46 46/23 = 2 Next, perform the multiplication: 800/40 = 20 20×7 = 140 Finally, add the results: 2 + 140 = 142

3. 54×68:18 + 5016:24 First, perform the multiplication: 54×68 = 3672 Then, divide 3672 by 18: 3672/18 = 204 Next, divide 5016 by 24: 5016/24 = 209 Finally, add the results: 204 + 209 = 413

4. 4900:14(62×205-12360) First, perform the subtraction inside the parentheses: 62×205-12360 = 12610 Next, divide 4900 by 14: 4900/14 = 350 Finally, multiply 350 by 12610: 350 × 12610 = 4413500

So, the values of the expressions are as follows:

1. 1690
2. 142
3. 413
4. 4413500
