Question

44−x2−−√, если x= −31.

Answer 1

Ответ:

54-√22²=54-√484=54-22=32

Answer 2

To evaluate the expression 44 - √(x^2), when x = -31, we substitute the value of x into the expression and perform the necessary calculations.

Given: x = -31

Now let's substitute the value of x into the expression:

44 - √((-31)^2)

Simplifying further:

44 - √(961)

The square root of 961 is 31, since √(961) = 31.

Therefore:

44 - 31 = 13

So, when x = -31, the value of the expression 44 - √(x^2) is 13.
