Answer 2

Expression 1: 635400 : 9 : 100

To find the value of this expression, we need to perform the division operation first, followed by the division operation again. Let's break it down step by step:

1. Divide 635400 by 9: 635400 / 9 = 70600. 2. Divide the result (70600) by 100: 70600 / 100 = 706.

Therefore, the value of the expression "635400 : 9 : 100" is 706.

Expression 2: 9004 · 50 – (52 360 - 57 · 65) 6

To find the value of this expression, we need to follow the order of operations (PEMDAS/BODMAS). Let's break it down step by step:

1. Multiply 9004 by 50: 9004 · 50 = 450200. 2. Subtract the result (450200) from the expression inside the parentheses: (52 360 - 57 · 65) = 52360 - 3705 = 48655. 3. Multiply the result from step 2 (48655) by 6: 48655 · 6 = 291930. 4. Subtract the result from step 3 (291930) from the result from step 1 (450200): 450200 - 291930 = 158270.

Therefore, the value of the expression "9004 · 50 – (52 360 - 57 · 65) 6" is 158270.

Expression 3: 603 . (1812 : 2) 30 - (790 · 970 - 92 142 : 6)

To find the value of this expression, we need to follow the order of operations (PEMDAS/BODMAS). Let's break it down step by step:

1. Divide 1812 by 2: 1812 : 2 = 906. 2. Multiply the result from step 1 (906) by 30: 906 · 30 = 27180. 3. Perform the division operation inside the parentheses: 92 142 : 6 = 15357. 4. Multiply 790 by 970: 790 · 970 = 766300. 5. Subtract the result from step 4 (766300) from the result from step 3 (15357): 15357 - 766300 = -750943. 6. Subtract the result from step 5 (-750943) from the result from step 2 (27180): 27180 - (-750943) = 778123.

Therefore, the value of the expression "603 . (1812 : 2) 30 - (790 · 970 - 92 142 : 6)" is 778123.
