Answer 2

To solve the given equations, let's solve them step by step.

Equation 1: √x = 2/3

To isolate the square root (√x), we need to square both sides of the equation:

(√x)² = (2/3)² x = (2/3)² x = 4/9

Therefore, the solution to Equation 1 is x = 4/9.

Now, let's move on to Equation 2: √x - 8 = 0

Adding 8 to both sides of the equation, we get:

√x = 8

To isolate x, we need to square both sides of the equation:

(√x)² = 8² x = 64

Therefore, the solution to Equation 2 is x = 64.

Lastly, let's solve Equation 3: 2√x - 9 = 0

Adding 9 to both sides of the equation, we get:

2√x = 9

Dividing both sides of the equation by 2, we get:

√x = 9/2

To isolate x, we need to square both sides of the equation:

(√x)² = (9/2)² x = (9/2)² x = 81/4

Therefore, the solution to Equation 3 is x = 81/4.

In summary, the solutions to the given equations are: Equation 1: x = 4/9 Equation 2: x = 64 Equation 3: x = 81/4
