Question

19- корень из ×^2 если ×=15

Answer 1

Ответ:

19✓x²=19✓15²=19*15=285

Answer 2

To calculate the expression √(x^2) where x = 15, you first need to substitute the value of x into the expression and then take the square root.

So, let's substitute x = 15 into the expression:

√(15^2)

Now, let's calculate the square of 15:

15^2 = 225

Finally, take the square root of 225:

√225 = 15

Therefore, the value of √(x^2) when x = 15 is 15.
