In this video, we condense expressions using the properties of logarithms.

In this video, we solve three questions (in order of ascending difficulty) where we solve exponential equations by using logarithms.

In this video, we solve two equations with rational exponents (fraction exponents). In order to solve equations with rational (fraction) exponents, you first isolate the value that is raised to the rational exponent. Then, you raise both...

How to do partial fractions with repeated linear factors? If you have something squared or cubed in the denominator, how does that change your setup for partial fractions problems? In this video we examine how a different problem will...

Find all six trig ratios given a point on the terminal side of theta. In this video we work this common type of problem. We use the Pythagorean Theorem to find "r" (hypotenuse), and then use the given "x" (adjacent) and "y" (opposite) to...

How can you add up an infinite number of values? In this video we derive the rule and learn how to find the sum of a geometric infinite series. I give a visual example of how we can add up an infinite number of terms in a geometric...

This video explains how to simplify quotients involving exponents. It covers the rule that when dividing with the same base, you subtract the exponents. The video also demonstrates how to handle a whole fraction raised to a power by...

China’s “One Belt, One Road” project is a massive plan to build roads, railways, ports, and power plants in over 60 countries to boost trade and global influence. While the initiative may help underdeveloped nations with new...

The tremendous growth happening in Africa presents humanity with a once-in-a-species opportunity: to make (nearly) an entire continent skip development of dirty fossil fuels, and be powered by renewable energy instead.

Tehran, the capital of Iran, is a city of 15 million people dealing with political oppression, environmental challenges, and economic struggles, despite its large oil wealth. Its modern history includes revolution, war, and resistance,...

Kinshasa, the capital of the Democratic Republic of the Congo, is Africa’s most populous city and one of the fastest growing in the world. Despite having rich natural resources and great potential, it struggles with deep poverty,...

Burning coal and natural gas to make electricity causes the most pollution globally, but policies like feed-in tariffs and renewable energy standards help encourage the switch to wind and solar. Texas has been successful in growing clean...

Bangalore, known as India’s “Silicon Valley,” is a major tech and innovation hub that plays a big role in the country’s economy, especially in the South, which is richer and more developed than the North. Southern states have higher...
