Question

X² = -3 это сколько x=?​

Answer 1

Нет ответа, т.к. любое число во второй степени не может быть отрицательным.

Answer 2

To find the value of x in the equation x² = -3, we need to take the square root of both sides. However, in this case, we encounter an issue because the square root of a negative number is not a real number, but a complex number.

The square root of -3 is √(-3), which can be represented as ±i√3, where "i" is the imaginary unit, and √3 is the positive square root of 3.

So, there are two complex solutions for x:

x = +i√3

x = -i√3

These values of x satisfy the equation x² = -3, as:

(+i√3)² = -(√3)² = -3

(-i√3)² = -(√3)² = -3
