Question

Обчислить если а=6 а+(а×8) 49-а×а (а+42)÷8

Answer 1

1)!!54
2) 13
3) 6
Вот так как-то

Answer 2

6+(6•8)
6+48
=54

49-6•6
49-36
=13

(6+42):8
48:8
=6

Answer 3

To calculate the expression, substitute the value of 'a' into the given expression and perform the arithmetic operations step by step:

a = 6

a + (a × 8) - (49 - a × a) × (a + 42) ÷ 8

Now, let's compute it:

a + (a × 8) = 6 + (6 × 8) = 6 + 48 = 54

(49 - a × a) = 49 - 6 × 6 = 49 - 36 = 13

(a + 42) ÷ 8 = (6 + 42) ÷ 8 = 48 ÷ 8 = 6

Now, substituting these values back into the expression:

54 - 13 × 6 = 54 - 78 = -24

So, the final result is -24.
