Answer 2

Ответ:

1) х≈2,09 , 2) х=11 , 3) х=20

Пошаговое объяснение:

1) 6ˣ=42

х=㏒₆(42)

х=㏒₆(6*7)

х=㏒₆(6)+㏒₆(7)

х=1+㏒₆(7)

2) 45+х=56

  х=56-45

3) 39-х=19

-х=19-39

-х=-20

Answer 3

To solve the equations, follow these steps for each equation:

1. 6× = 42

2. 45 + х = 56

3. 39 - х = 19

4. 6× = 42: To solve for × (x), divide both sides of the equation by 6: 6×/6 = 42/6 x = 7

5. 45 + х = 56: To solve for х (x), subtract 45 from both sides of the equation: 45 + х - 45 = 56 - 45 х = 11

6. 39 - х = 19: To solve for х (x), subtract 19 from both sides of the equation: 39 - х - 19 = 19 - 19 -х = 0

Now, divide both sides by -1 to isolate x: -х / -1 = 0 / -1 x = 0

The solutions to the equations are:

1. x = 7
2. x = 11
3. x = 0
