Question

Вычисли значение выражения 9−√x2, если x= 2.

Answer 1

Если х=2, то подставим в уравнение, получим:

9-√2*2= 9-√4=9-2=7.

Ответ: 7

Answer 2

To calculate the value of the expression 9 - √(x^2) when x = 2, we first need to substitute the value of x into the expression and then perform the necessary calculations.

Given x = 2, we have:

9 - √(2^2)

Now, calculate the square of 2:

2^2 = 2 * 2 = 4

Now, find the square root of 4:

√4 = 2

Now, substitute the value back into the expression:

9 - 2 = 7

So, the value of the expression 9 - √(x^2) when x = 2 is 7.
