Find the required point be `P(x_1, y_1)dot` The tangent to the curve `sqrt(x)+sqrt(y)=4` at which tangent is equally inclined to the axes.

Explanation

To find the required point \( P(x_1, y_1) \) where the tangent to the curve \( \sqrt{x} + \sqrt{y} = 4 \) is equally inclined to the axes, we will follow these steps:

### Step 1: Differentiate the curve
We start with the equation of the curve:
\[ \sqrt{x} + \sqrt{y} = 4 \]
To find the slope of the tangent, we differentiate both sides with respect to \( x \).
