PROPORTION METHOD The proportion method is used in both of these expressions. A proportion is an equation that says that two ratios are equivalent. The use of cross multiplying is in use in both expressions as well. I believe the first expression (#56) uses the extreme-means property; the product of the means is equal to the product of the extremes. #56.

understand why I should be forced to “learn” concepts that are completely useless to me. Again‚ I have never once had to use algebra outside of the classroom. Any time I have had to solve some sort of a logic-based issue‚ I have done so without knowing linear equations‚ functions‚ graphs‚ or sets. I have solved problems on my own or with the help of others without any knowledge of algebra‚ and I don’t suspect that will change anytime

Mathematics Assignment 153. Explain the negative exponent rule and give an example. The main rule for a negative exponent is to always first make it into a positive before you start simplifying. For example y^-4+7=x The first thing you would do is write it as this 1/y^4+7=x Once this is completed you can then simplify. 154. How do you know if an exponential expression is simplified? You can tell if an exponential expression is simplified when it brought down to the lowest possible simplification
