Question

Solve for x, where x is a real number.

`\sqrt{x-8 =5`

Answer 1

The value of x in the equation √x - 8 = 5 is 33.

Step-by-step explanation:

To solve for x, where x is a real number in the equation √x - 8 = 5, we need to isolate x.

First, we can square both sides of the equation to get rid of the square root.

Here's the step-by-step solution:

1. Square both sides of the equation: (√x - 8)^2 = 5^2 which simplifies to x - 8 = 25.
2. Add 8 to both sides to isolate x: x - 8 + 8 = 25 + 8, which gives x = 33.

Therefore, the value of x is 33.
