Решитн уравнение 0.64-у^2=0

Answer 1

0.64-у^2=0
-y^2=-0.64 (разделим всё уравнение на -1)
y^2=0.64
y=+- корень из 0.64
у=+- 0.8

Answer 2

To solve the equation 0.64 - y^2 = 0, we can follow these steps:

1. Move the constant term to the other side of the equation: -y^2 = -0.64

2. Multiply both sides by -1 to change the sign: y^2 = 0.64

3. Take the square root of both sides of the equation: y = ±√(0.64)

   The square root of 0.64 is ±0.8.

Therefore, the solutions to the equation 0.64 - y^2 = 0 are y = 0.8 and y = -0.8.
