Пошаговое объяснение:

5).  y^2-1=0.  y^2=1.  y1=1,  y2=-1

6).  y^2-2=0.   y^2=2.  y1=√2,  y2=-√2.  что означают остальные цифры - не поняла.

Answer 2

It seems like there might be a typo or a formatting issue in the equations you've provided. Let me clarify:

1. $y^2 - 1 = 0$
2. $y^2 - 2 = 0.164$

For the first equation, $y^2 - 1 = 0$, you can solve it as follows:

$y^2 - 1 = 0$

Add 1 to both sides:

$y^2 = 1$

Take the square root of both sides:

$y = \pm 1$

So, for this equation, the solutions are $y = 1$ and $y = -1$.

For the second equation, $y^2 - 2 = 0.164$, you can solve it as follows:

$y^2 - 2 = 0.164$

Add 2 to both sides:

$y^2 = 2.164$

Take the square root of both sides:

$y = \pm \sqrt{2.164}$

Calculating the square root of 2.164, you get two real solutions:

$y \approx 1.47 \text{ and } y \approx -1.47$

So, for this equation, the solutions are $y \approx 1.47$ and $y \approx -1.47$.
