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.

$\mid -8 \mid$ = 8

To simplify radicals you have to know the root. Either $\sqrt [2]{16}$ or $\sqrt [3]{64}$

For $\sqrt [2]{16}$

we know that $\sqrt {4}$ $\sqrt {4}$ =  $\sqrt {16}$

that then turns to 2*2

which then would = 4

For $\sqrt [3]{64}$

we know that $\sqrt {4}$ $\sqrt {4}$ $\sqrt {4}$ =$\sqrt {64}$

then would turn into 2*2*2

which would = 8
