Answer 2

To solve the expression [500-(3500:700x80-40x9)x(64:8)]:9-(72:6):(81:27), let's break it down step by step:

Step 1: Simplify the innermost parentheses. Within the innermost parentheses, we have two multiplication operations: 700x80 and 40x9. Let's solve them first:

700x80 = 56000 40x9 = 360

Step 2: Calculate the expression within the square brackets. [3500:56000-360]:9-(72:6):(81:27)

3500:56000-360 = 0.0625

Step 3: Simplify the remaining expression. 0.0625:9-(72:6):(81:27)

72:6 = 12 81:27 = 3

Step 4: Calculate the remaining expression. 0.0625:9-12:3

To calculate the division first, we have:

0.0625:9 = 0.006944444444444444

Then, we have:

0.006944444444444444 - 12:3

12:3 = 4

Finally:

0.006944444444444444 - 4 = -3.9930555555555556

Therefore, the result of the expression [500-(3500:700x80-40x9)x(64:8)]:9-(72:6):(81:27) is approximately -3.9930555555555556.
