This topic covers: - Simplifying rational expressions - Multiplying, dividing, adding, & subtracting rational expressions - Rational equations - Graphing rational functions (including horizontal & …

A worked example of simplifying elaborate expressions that contain radicals with two variables. In this example, we simplify √ (60x²y)/√ (48x). Created by Sal Khan and Monterey Institute for …

Which expression is equivalent to the following complex fraction? d 4 3 d Choose 1 answer: d 4 ⋅ d 3

Video transcript - [Voiceover] Let's see if we can simplify this expression and like always, pause the video and have a go at it. Now this one is interesting because it involves two variables, but …

To solve the equation (3/4)x + 2 = (3/8)x - 4, we first eliminate fractions by multiplying both sides by the least common multiple of the denominators. Then, we add or subtract terms from both …

In this unit, we review exponent rules and learn about higher-order roots like the cube root (or 3rd root). We'll learn how to calculate these roots and simplify algebraic expressions with radicals.

And what's nice about this, this is pretty straightforward to simplify. 12 divided by three is four, and w to the seventh divided by w-squared, well, we could divide both by w-squared or you could …

If you want to use the formula, you need to know how to replace the variables with the appropriate values and do the math. The values given to the variables could be decimals, fractions, mixed …
