| (because is the same thing as 2) |

Find on your calculator.
Find on your calculator.
Double your answer to #2 on your calculator.
So, did it work?
Good! Then let’s try another one. Simplify , using the same steps I took to simplify .
Check your answer on the calculator. Did it work?
Oh yeah, one final question: what is ? How can you test your answer?
