Question

-x(x+2+(x+5²)) при x=-3/8

Answer 1

Ответ:

3/8(-3/8+(-3/8)+(-3/8+5)^2)=3963/512 или ≈7,74023

Answer 2

To evaluate the expression -x(x + 2 + (x + 5²)) when x = -3/8, you'll need to substitute -3/8 for x in the expression and perform the calculations step by step.

First, let's replace x with -3/8:

-(-3/8)(-3/8 + 2 + (-3/8 + 5²))

Now, let's simplify the expression inside the parentheses:

-(-3/8)(-3/8 + 2 + (-3/8 + 25))

Next, continue simplifying:

-(-3/8)(-3/8 + 2 - 3/8 + 25)

Now, combine like terms:

-(-3/8)(24/8 + 25)

Next, simplify the expression inside the parentheses:

-(-3/8)(49/8)

Now, multiply the values:

-(-3/8) * (49/8) = (3/8) * (49/8)

Finally, multiply the numerators and denominators:

(3 * 49) / (8 * 8) = 147 / 64

So, the value of the expression -x(x + 2 + (x + 5²)) when x = -3/8 is 147/64.
