Gain insights into Java programming by exploring conditional statements, loops, math, logic, inheritance, generics, and arraylists, to become an intermediate Java developer.

Learn Java for free with this interactive course, and get a handle on one of the most popular programming languages in the world.

You'll start with a simple hello world program and proceed to cover common concepts such as Conditional Statements, Loop Statements, Math, and Logic in Java, before moving on to more advanced concepts like Inheritance, Generics, and ArrayLists, along with much more.

By the time you're done, you'll be an intermediate level Java developer, ready to take on your own projects.

# Problem statement 

Just like a Pokemon evolves, so do the expressions you work with. The mathematical expression given below is one such difficult expression, and hence, it is a challenge for you to solve! 

Below is an *illustration* showing the **expression** you need to compute:
    

# Coding exercise

Write a code in which you:
* First, compute the **respective powers** of *two* **floating-point** variables `x` and `y`. 
* Then **Add** them after taking **powers**. 
* Then, compute the **absolute** value of **floating-point** `z`.
* Subtract this from the above-computed addition value.
* Now take **Cube Root** of the answer. 
* Use `inbuilt functions` to calculate this expression

Only write the code where instructed in the snippet below. You need to calculate the value of the expression, and then store your final result in the variable `answer`.  The **return** statement and the **variable** to be returned are already mentioned for you. Don't worry too much about the return statement for the moment, and just set the value of the `answer` correctly. 

Test your code against our cases and see if you can pass them.

The solution is given in case​ you get stuck, and the next lesson will include a review of the solution, but it is **highly recommended** that you try it yourself first!

**Good Luck!**

In this exercise, you need to compute the expression.
