Answer 2

Let's solve each expression step by step:

1. 326 * (672 + 448) / (800713 - 800633) First, perform the operations inside the parentheses: = 326 * 112 / (800713 - 800633) = 36512 / 80 = 456.4

2. (26230 / 86 * 206 + 2886 * 86) - 456 * 507 Perform the division first: = 305 * 206 + 2886 * 86 - 456 * 507 Now perform the multiplications: = 62830 + 248796 - 231192 = 4634

3. (832 * 9150462 - 149748) - (784689 - 781543) Perform the first multiplication and subtraction: = 7623547584 - 149748 - (784689 - 781543) Continue with the second subtraction: = 7623547584 - 149748 - 3146 = 7623403840

4. 604 * 706 / 8 - (302000 - 39430) / (4960 / 80) * 12 First, perform the multiplication and division inside the parentheses: = 604 * 706 / 8 - (262570) / (62) * 12 Perform the division and multiplication: = 425624 / 8 - 4242 * 12 = 53153 - 50904 = 2249

5. 30 * 3000 - 907788 / (98 * 29 - 132370 / 62) * 87 Perform the division inside the parentheses first: = 30 * 3000 - 907788 / (98 * 29 - 2138.71) * 87 Perform the subtraction inside the parentheses: = 30 * 3000 - 907788 / (2842.71) * 87 Now perform the division and multiplication: = 30 * 3000 - 319.73 * 87 = 90000 - 27800.51 = 62199.49

So, the values of the expressions are:

1. 326 * (672 + 448) / (800713 - 800633) = 456.4
2. (26230 / 86 * 206 + 2886 * 86) - 456 * 507 = 4634
3. (832 * 9150462 - 149748) - (784689 - 781543) = 7623403840
4. 604 * 706 / 8 - (302000 - 39430) / (4960 / 80) * 12 = 2249
5. 30 * 3000 - 907788 / (98 * 29 - 132370 / 62) * 87 = 62199.49
