Question

Решите уравнение √5x-1=3

Answer 1

Вариант 1

√5*x-1=3

√5*х = 4

х = 4/√5

Вариант 2

√(5x)-1=3

√(5x) = 4

5х = 16

х = 3,2

Answer 2

1. √5х=4
2. х=3.2
3. Ответ х=3.2

Answer 3

To solve the equation √(5x) - 1 = 3, follow these steps:

Step 1: Isolate the square root term. Add 1 to both sides of the equation to move the constant term to the right side:

√(5x) = 3 + 1 √(5x) = 4

Step 2: Square both sides of the equation to eliminate the square root. By squaring both sides, we get:

(√(5x))^2 = 4^2 5x = 16

Step 3: Isolate x. To solve for x, divide both sides by 5:

x = 16 / 5

Step 4: Simplify the result:

x = 3.2

So, the solution to the equation is x = 3.2.
