Pre-Calculus, Week 4

When Multiplying a Radical with another radical you multiply the numerator with the numerator and the denominator with the denominator. If you have to equals like (7-\sqrt{6})(4+\sqrt{6})  you would use the foiling method or distributive property. Make sure you always simplify after you find the answer to make it as low as possible.

 

 

Arranging mixed radicals into descending order (greatest to least). The reason why i feel like this is important is because i get confused sometimes on whether or not i should change into an entire number or keep ir mmixedd. I find now that it is easier fofr me to change it into an entire number. In the example belong i’m going to show the method i use to solve arranging mixxed numbers to greatest to least.
