Answer 2

To solve the expression 4,3*(-7) -9, 6:(9, 2-10, 8), let's break it down step by step:

Step 1: Evaluate the expression within parentheses (9, 2-10, 8): 2 - 10 = -8

Step 2: Simplify the expression 6:(9, -8): The division operator ":" denotes division, so 6:(9, -8) means 6 divided by the values 9 and -8.

6 ÷ (9, -8) = 6 ÷ 9 ÷ -8 = 6/9 ÷ -8 = 2/3 ÷ -8 = (2/3) * (-1/8) [Dividing by a negative number is the same as multiplying by its reciprocal]

Step 3: Evaluate the expression 4,3*(-7): 4,3 * (-7) = 12 * (-7) = -84

Step 4: Combine the results from Step 3 and Step 2: (-84) - (2/3) * (-1/8) = -84 + (2/3) * (1/8) = -84 + 2/24 = -84 + 1/12 = -84 + 0.0833 ≈ -83.9167

Therefore, the result of the expression 4,3*(-7) -9, 6:(9, 2-10, 8) is approximately -83.9167.
