Pupil outcome: I can identify the highest square factor of any term including those written with algebra. Key learning points: - Numbers can be classified as surds or not surds. - Square factors of numerical and algebraic terms can be...

Pupil outcome: I can appreciate the structure that underpins multiplication of surds. Key learning points: - The square root operation is equivalent to the exponent 0.5 where the base is the term under the square root. - You can deduce...

Pupil outcome: I can appreciate the structure that underpins addition of surds. Key learning points: - An unknown value is represented by a letter. - An unevaluated surd can be thought of as an unknown value. - Each simplified surd has a...

Pupil outcome: I can identify, from their equations or graphs, whether two lines are perpendicular. Key learning points: - If two equations are written in the form y = mx + c then you can identify if they are perpendicular. - If the...

Pupil outcome: I can explain how William Blake presents power in society in 18th century London. Key learning points: - Blake’s poem ‘London’ is a condemnation of the inequality and oppression that pervaded society in 18th century...

In this video, we will define imaginary numbers and examine the complex number system.

In this video, we solve equations with radicals. In the first example, we solve an equation with a single radical. In the second problem, we solve an equation with two radicals.

In this video, we learn how to solve quadratic equations with the quadratic formula. We examine one example where we have to simplify the radical, and a second example with a nonreal solution.

In this video, we learn the 1-2-3 method for memorizing the points on the unit circle. This is not a video where we derive the unit circle, I have other videos about that. Here, we just try to memorize the unit circle so that we can...

How do you solve equations with radicals? How do you solve equations with more than one radical, or with radicals on both sides? This video includes two examples of how to solve this type of problem.

How to simplify when you add, subtract, or multiply radical expressions

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

In this video, we discuss how to simplify expressions with rational exponents. When your exponent is a fraction, how can you rewrite it with a radical? When you have a radical, how can you rewrite that as an exponent?

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

In this math video we will learn two ways to simplify a radical expression. We will first understand that an exponent of 2 means to multiply the base by itself. We will learn to multiply radicals with the same index, you multiply the...

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.

Polyacrylamide gel electrophoresis (PAGE) uses a gel matrix formed by polymerizing acrylamide and bis-acrylamide through free radicals generated by TEMED and APS. This exothermic polymerization forms linear chains cross-linked into a 3D...

Thomas Paine's visionary writings, advocating freedom and democracy, were instrumental in shaping the United States' fight for independence. Explore his remarkable journey, from campaigning for higher pay as a tax collector in England,...

Aunque todavía está esta en una etapa incipiente, la nanotecnología tiene la capacidad de cambiar el mundo en el que vivimos. ¿Qué es y cómo podría usarse en el futuro?

Twig - Química - Los átomos y los enlaces -...

Still in its early stages, nanotechnology has the potential to change our world. What is it and how could it be used in the future? Chemistry - Atoms And Bonding - Learning Points. Nanotechnology is engineering on the smallest scale....

In organic chemistry, electrophiles, nucleophiles, and free radicals are the three key types of reactive intermediates. Electrophiles are electron-deficient species that seek out electrons, making them attracted to regions of high...

By the end of this learning object, the student will be able to: Use the quadratic formula to solve quadratic equation.

It’s the oldest political party in the United States, but how was the Democratic Party formed and what contributions has it made to U.S. society since?

Inspired by the religious fervor of the Second Great Awakening, Joseph Smith founded the most widely-practiced religion founded in the United States, the Mormon faith.
