Question

X^2=57 решите уравнение

Answer 1

$x^2=57\\x= \sqrt{57} \\x =-\sqrt{57}$

Answer 2

To solve the equation x^2 = 57, you need to find the values of x that satisfy the equation. Let's proceed with the solution:

x^2 = 57

To find the value of x, we need to take the square root of both sides of the equation. However, since there's a square term involved, we'll consider both the positive and negative square roots:

1. Positive square root: x = √57

2. Negative square root: x = -√57

Now, let's calculate the approximate values of x using a calculator:

1. Positive square root: x ≈ √57 ≈ 7.55 (rounded to two decimal places)

2. Negative square root: x ≈ -√57 ≈ -7.55 (rounded to two decimal places)

So, the solutions to the equation x^2 = 57 are approximately x ≈ 7.55 and x ≈ -7.55.
