Question

12,5:(-0,5)³-0,25×(-8)

Answer 1

Ответ:

-98

Пошаговое объяснение:

1) 12,5 : (-0,5)³ = 12,5 : (-0,5 * (-0,5) * (-0,5)) = 12,5 : (-0,125) = -100

2) 0,25 * (-8) = -2

3) -100 - (-2) = -100 + 2 = -98

Answer 2

To solve the expression, let's break it down step by step:

1. Start with the first term: 12,5 ÷ (-0,5)³

   To simplify this, we need to cube the denominator (-0.5). (-0.5)³ = (-0.5) × (-0.5) × (-0.5) = -0.125

   Now we can rewrite the expression as: 12.5 ÷ (-0.125)

   Dividing 12.5 by -0.125 gives us -100.

2. Move on to the second term: -0.25 × (-8)

   Multiplying -0.25 by -8 gives us 2.

Now we can combine the results from both terms:

-100 + 2 = -98

Therefore, the value of the expression 12,5:(-0,5)³-0,25×(-8) is -98.
