Q: Give the output of the following:

Math.pow(36, 0.5) + Math.cbrt(125) + Math.ceil(4.2) + Math.floor(7.9)

 

Let's analyze the given expression and the output of the Java Math functions:

Expression:

Math.pow(36, 0.5) + Math.cbrt(125) + Math.ceil(4.2) + Math.floor(7.9)
        

Explanation:

1. Math.pow(36, 0.5):

   The Math.pow(x, y) method returns x raised to the power of y.
   Math.pow(36, 0.5) calculates the square root of 36.
   √36 = 6.0

2. Math.cbrt(125):

   The Math.cbrt(x) method returns the cube root of x.
   Math.cbrt(125) calculates the cube root of 125.
   ∛125 = 5.0

3. Math.ceil(4.2):

   The Math.ceil(x) method returns the smallest integer greater than or equal to x.
   Math.ceil(4.2) returns the smallest integer greater than or equal to 4.2.
   Math.ceil(4.2) = 5.0

4. Math.floor(7.9):

   The Math.floor(x) method returns the largest integer less than or equal to x.
   Math.floor(7.9) returns the largest integer less than or equal to 7.9.
   Math.floor(7.9) = 7.0

Calculating the Sum:

Adding these values together:
6.0 + 5.0 + 5.0 + 7.0 = 23.0

Conclusion:

The output of the expression is: 23.0
