Answer 2

To evaluate the expression:

57/15 - (71/12 - (429/60 - (21)5 - 15/6))

Let's break it down step by step:

1. Simplify the innermost expression within the parentheses: (21)5 = 21 * 5 = 105.

The expression now becomes:

57/15 - (71/12 - (429/60 - 105 - 15/6))

2. Simplify the next innermost expression within the parentheses: 429/60 = 7.15.

The expression now becomes:

57/15 - (71/12 - (7.15 - 105 - 15/6))

3. Simplify the next innermost expression within the parentheses: 7.15 - 105 = -97.85.

The expression now becomes:

57/15 - (71/12 - (-97.85 - 15/6))

4. Simplify the next innermost expression within the parentheses: 15/6 = 2.5.

The expression now becomes:

57/15 - (71/12 - (-97.85 - 2.5))

5. Simplify the expression within the parentheses: -97.85 - 2.5 = -100.35.

The expression now becomes:

57/15 - (71/12 - (-100.35))

6. Simplify the expression within the parentheses: 71/12 = 5.9167 (rounded to 4 decimal places).

The expression now becomes:

57/15 - (5.9167 - (-100.35))

7. Simplify the expression within the parentheses: 5.9167 - (-100.35) = 106.2667.

The expression now becomes:

57/15 - 106.2667

8. Simplify 57/15 = 3.8 (rounded to 1 decimal place).

The final expression becomes:

3.8 - 106.2667

9. Subtract 106.2667 from 3.8:

3.8 - 106.2667 = -102.4667 (rounded to 4 decimal places).

Therefore, the value of the expression 57/15 - (71/12 - (429/60 - (21)5 - 15/6)) is approximately -102.4667.
