x+2=6 and its under a square root thing
To find the value of x when it is under a square root, you need to isolate x on one side of the equation. Let's solve the equation step by step:
1. Start with the given equation: x + 2 = 6.
2. To isolate x, subtract 2 from both sides of the equation:
(x + 2) - 2 = 6 - 2.
This simplifies to: x = 4.
3. Now, we have obtained the value of x as 4. However, since x is under a square root, we need to evaluate the square root of x.
4. Taking the square root of both sides of the equation gives us: √x = √4.
The square root of 4 is 2, so we have: √x = 2.
5. To solve for x, we need to square both sides of the equation:
(√x)^2 = 2^2.
This simplifies to: x = 4.
Therefore, the value of x that satisfies the equation x + 2 = 6, with x under a square root, is x = 4.
