This week we started our new unit on absolute values and radicals. It was a very short week and most of it was review from grade 10 math, except for the new term of what an absolute value is.  Something I found hard to do at first was turning entire radicals into a mixed radical.

example

first we need to find two numbers that multiply to 72, with one of them being a perfect square.

because 9 is a perfect square of 3 we can take that and put it as a coefficient leaving only the 8 under the root symbol.

this is our final answer.
