Question

|2а-3|5+а|| при а=-3

Answer 1

2 × 3-3×5+3= 24 так как в модулях знак минус убирается

Answer 2

To evaluate the expression |2a - 3|5 + a| when a = -3, we substitute the value of 'a' into the expression and perform the calculations step by step:

Step 1: Substitute a = -3 into the expression: |2(-3) - 3|5 + (-3)|

Step 2: Perform the operations inside the absolute value signs: |(-6) - 3|5 + (-3)|

Step 3: Perform the absolute value calculation: |-9|5 + |-3|

Step 4: Evaluate the absolute values: 9 * 5 + 3

Step 5: Perform the multiplication and addition: 45 + 3

Step 6: The final result is: 48
