Question

Упростите числовое выражение: 1. (-6)x(-9+4)-4x(-6) если что x это знак умножения 2. (-7)x(-53+125)-53 3. 44x(-99-1)+98x44

Answer 1

Пошаговое объяснение:

1

$- 6 \times - 9 + 4 \times - 6 - 4 \times - 6 = - 6 \times - 9 = 54$

2

$( - 7 + 1)( - 53) - 7 \times 125 = - 6 ( - 53) - 7 \times 125 = - 6( - 53 + 125) - 125 = - 6 \times 72 - 125 = 557$

3

$44( - 99 - 1 + 98) = - 2 \times 44 = - 88$

Answer 2

1. (-6) x (-9 + 4) - 4 x (-6)

First, simplify the parentheses: (-6) x (-5) - 4 x (-6)

Next, perform the multiplications: 30 - (-24)

To simplify the expression, remember that subtracting a negative number is the same as adding a positive number: 30 + 24

Finally, perform the addition: 54

So, the simplified expression is 54.

2. (-7) x (-53 + 125) - 53

First, simplify the parentheses: (-7) x (72) - 53

Next, perform the multiplication: -504 - 53

Finally, perform the subtraction: -557

So, the simplified expression is -557.

3. 44 x (-99 - 1) + 98 x 44

First, simplify the parentheses: 44 x (-100) + 98 x 44

Next, perform the multiplications: -4400 + 4312

Finally, perform the addition: -88

So, the simplified expression is -88.
