Question

Сравни 450-50*540-400678-а*786-а

Answer 1

450 - 50 * 540 - 400
400 * 140
400 > 140

678 - а * 786 - а

Например: а = 140

678 - 140 * 786 - 140
538 * 646
678 - а < 786 - а

Answer 2

450 минус 50 больше 678а меньше 786а

Answer 3

To compare the given expression, we need to find the value of 'a' and then simplify the expression. Let's proceed step by step:

1. Given expression: 450 - 50 * 540 - 400678 - a * 786 - a

2. First, let's simplify the expression by performing the arithmetic operations:

   450 - 50 * 540 = 450 - 27000 = -26550

   • 26550 - 400678 - a * 786 - a

3. Now, we need to factor out 'a' from the last two terms:

   • 26550 - 400678 - a(786 + 1) = -26550 - 400678 - 787a

4. The final simplified expression is: -26550 - 400678 - 787a

Since there is no specific value for 'a' provided in the question, we cannot further simplify the expression or determine its numeric value. It depends on the value of 'a' in the context of the problem.
