Week 3 – Absolute values and Radicals

This week we had learned about absolute values and simplifying radicals. For absolute values we had learned about whatever is in-between the two lines will always be positive.

= 8

To simplify radicals you have to know the root. Either or 

For 

we know that   =  

that then turns to 2*2

which then would = 4

For 

we know that    =

then would turn into 2*2*2

which would = 8
