Question

Compute: z = \sqrt{x-y}
Ex: If the input is 4.0 3.0, then the output is:

1.0

Answer 1

For the input values of x = 4.0 and y = 3.0, the computed value of z = √(4.0 - 3.0) is 1.0.

Step-by-step explanation:

To compute z = √(x - y), we substitute the given values: x = 4.0 and y = 3.0. Plugging these values into the equation gives us z = √(4.0 - 3.0).

Therefore, z = √(1.0), which simplifies to z = 1.0. The square root of 1 is 1 itself. So, for the input values of x = 4.0 and y = 3.0, the value of z is indeed 1.0.

In this equation, z represents the square root of the difference between x and y. When x = 4.0 and y = 3.0, the difference between them is 1.0 (4.0 - 3.0 = 1.0). Taking the square root of this difference results in the final value of 1.0 for z. This computation involves a straightforward substitution of values into the formula z = √(x - y) and evaluating the expression, resulting in the given output.

Answer 2

The value of z for the input x = 4.0 and y = 3.0 can be calculated as follows:

z = \sqrt{x-y}
= \sqrt{4.0 - 3.0}
= \sqrt{1.0}
= 1.0

So the output is 1.0
