Answer 2

To solve each expression, follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Here are the solutions for each expression:

а) 97 + 13662 / 27 + 36 * 1944 - 43 * 809

First, perform the division: 13662 / 27 = 506 Next, perform the multiplication: 36 * 1944 = 69984 and 43 * 809 = 34787

Now, the expression becomes: 97 + 506 + 69984 - 34787

Finally, perform the addition and subtraction: 97 + 506 + 69984 - 34787 = 3540

б) 988 + 1530 * 12 * 6 - 38 * (12 * 6 - 38) * 15

First, perform the multiplication inside the parentheses: 12 * 6 = 72, and 38 * 72 = 2736

Now, the expression becomes: 988 + 1530 * 12 * 6 - 38 * 2736 * 15

Next, perform the multiplication: 1530 * 12 * 6 = 110160 and 38 * 2736 * 15 = 1555200

Now, the expression becomes: 988 + 110160 - 1555200

Finally, perform the addition and subtraction: 988 + 110160 - 1555200 = -442052

в) 4080 - (352719 - 57837) / 98 + 307 * 107

First, perform the subtraction inside the parentheses: 352719 - 57837 = 294882

Now, the expression becomes: 4080 - 294882 / 98 + 307 * 107

Next, perform the division: 294882 / 98 = 3018

Now, the expression becomes: 4080 - 3018 + 307 * 107

Next, perform the multiplication: 307 * 107 = 32849

Finally, perform the addition and subtraction: 4080 - 3018 + 32849 = 35643

г) 40 * (207 * 54 - 793) - 270000 / 18

First, perform the multiplication inside the parentheses: 207 * 54 = 11178, and 11178 - 793 = 10385

Now, the expression becomes: 40 * 10385 - 270000 / 18

Next, perform the division: 270000 / 18 = 15000

Now, the expression becomes: 40 * 10385 - 15000

Next, perform the multiplication: 40 * 10385 = 415400

Finally, perform the subtraction: 415400 - 15000 = 400400

д) 215 * (368 - 274) + 68 * (127 + 128)

First, perform the subtraction inside the parentheses: 368 - 274 = 94, and 127 + 128 = 255

Now, the expression becomes: 215 * 94 + 68 * 255

Next, perform the multiplication: 215 * 94 = 20210, and 68 * 255 = 17340

Finally, perform the addition: 20210 + 17340 = 37550

е) (8222 - 4781) / 37 - (1519 - 637) / 42

First, perform the subtraction inside the parentheses: 8222 - 4781 = 3441, and 1519 - 637 = 882

Now, the expression becomes: 3441 / 37 - 882 / 42

Next, perform the divisions: 3441 / 37 ≈ 92.7838, and 882 / 42 = 21

Finally, perform the subtraction: 92.7838 - 21 ≈ 71.7838

Please note that the answers are rounded to several decimal places where necessary.
