Throughout this series we’ve mostly talked about pairs of electrons, but electrons don’t always have a buddy. An atom or group of atoms with a single unpaired electron is called a radical. In this episode of Crash Course Organic...

Hank tells us about new research into the question of how animals navigate from place to place - while the problem is still unresolved, we do have some hypotheses, and they all involve something called "magnetoreception."

New ReviewIn this shorts video we will learn about perfect squares & cubes. We will understand the relationship between squaring a number and find the square root of a number. We will also understand the relationship between cubing a number and...

In this video Professor Justin Champion discusses the Putney Debates, a crucial moment in the history of ideas to come out of the English Civil War.

In this video Professor Justin Champion introduces the diggers, levellers and ranters of the English Civil War.

This video discusses how to simplify radical expressions involving fractions and/or division

In this video, we discuss how to add and subtract radicals.

In this video, we discuss how to multiply terms that have radicals.

In this math video we will rewrite a radical using exponents. We will be given a radical expression and four exponential expressions. We will review the rule for writing a radical using exponents. We will identify the correct solution.

Rancidity refers to the complete or incomplete hydrolysis or oxidation of fats and oils when exposed to air, light, moisture, and bacterial activity; this generally occurs in food items, making them undesirable for consumption. In more...

Bond fission, the process of breaking chemical bonds, can occur in two ways: homolytic and heterolytic. In homolytic fission, the bond breaks evenly, with each atom receiving one electron, resulting in the formation of free radicals. In...

By 1848, Europe was engulfed in revolutionary fervor, driven by demands for democratic reforms and national autonomy. While some countries embraced change, like Denmark and the Netherlands, others, such as Russia under Emperor Nicholas...

Multiplying Surds: Simplification: This video explains what simplifying a surd means and how to simplify surds by multiplication. The three multiplication rules are explained with examples. Practice question and answer using the concept...

This video explains what a surd is and how to find out if a root is a surd or not a surd. It provides an introduction to understanding surds, which is crucial before studying how to manipulate surds. Practice questions and answers are at...

when you are learning to complete rationalizing the denominator, a problem like this is a great way make sure that you understand what you are doing and review your skillls with radicals.

Chinese scholar and literary translator Michael Berry (UCLA) describes differences between simplified and traditional Chinese characters and the politics associated with both.

Find the absolute value of a number by using a number line.

“Identify Extraneous Solutions” will review the different methods of how to test equations for extraneous solutions.

This video will explain and demonstrate how to simplify radical expressions.

👉 Learn how to find the derivative of a function using the power rule. The derivative of a function, y = f(x), is the measure of the rate of change of the function, y, with respect to the variable x. The process of finding the derivative...

Rancidity refers to the complete or incomplete hydrolysis or oxidation of fats and oils when exposed to air, light, moisture, and bacterial activity; this generally occurs in food items, making them undesirable for consumption. In more...

👉 Learn how to evaluate the limit of a function by rationalizing the radical. The limit of a function as the input variable of the function tends to a number/value is the number/value which the function approaches at that time. The limit...
