Question

-12с в 3 степени при с= -1/2

Answer 1

-12с³=-12*(-1/2)³=-12*(-1/8)=3/2=1 1/2=1,5

Answer 2

To evaluate the expression -12c^3 when c = -1/2, simply substitute the value of c into the expression and perform the calculations:

-12 * (-1/2)^3

Now, let's solve this step by step:

1. First, calculate the cube of -1/2: (-1/2)^3 = (-1/2) * (-1/2) * (-1/2) = -1/8

2. Next, multiply -12 by the result: -12 * (-1/8) = -(-12/8) = 12/8 = 3/2

So, when c = -1/2, the expression -12c^3 evaluates to 3/2.
