Precalc 11 – Week 3

This week in Precalc we started unit 2.  We learned about an absolute value of a real number which is how far a number is from 0 and positive numbers always equal a positive number.

Ex :

|2| = 2

|-4|= 4

We also learned how to simplify radical expressions which was a good reminder on knowing how to simplify entire and mixed radicals.

Ex :

\sqrt[3]{24x^3y^4}

 

2xy \sqrt[3]{3y}

x and y are real numbers
