## Learn Algebra 17 : Radical Expressions

New Video Everyday at 1 PM EST!!! [ Click Notification Bell ]

This time I cover Radical Expressions in mass detail. What is a radical expression and how do you simplify them. I also cover Rational Exponents.

I was asked by a local teacher to create an Algebra course that quickly reviewed all the key knowledge required. This course is centered around showing how to solve Algebra problems. For best results copy down the problem, watch me solve it, and then solve it on your own.

In upcoming videos I’ll cover Graphing, Systems of Equations, Quadratic Equations, Matrices, Polynomials, Functions, Rational Equations and so much more.

## Reference Variable in Java

Before We Started with the Reference variable we should know about the following facts.

**1. **When we create an object(instance) of class then space is reserved in heap memory. Let’s understand with the help of an example.

Demo D1 = new Demo();

Now, The space in the heap Memory is created but the question is how to access that space?.

Then, We create a Pointing element or simply called Reference variable which simply points out the Object(the created space in a Heap Memory).

**Understanding Reference variable **

1. Reference variable is used to point object/values.

**2. **Classes, interfaces, arrays, enumerations, and, annotations are reference types in Java. Reference variables hold the objects/values of reference types in Java.

3. Reference variable can also store null value. By default, if no object is passed to a reference variable then it will store a null value.

**4. **You can access object members using a reference variable using **dot **syntax.

## Scope of a Variable In Java [With Coding Example]

### Introduction

Programmers define the scope of a Variable in Java that tells the compiler about the region from where a variable is accessible or visible. The scope of a variable in Java is static by nature. It means we have to declare it at compile time only. In this article, you will learn about the scope of a Java variable along with its types
