Intermediate Algerbra

............
I'm in desperate need of help, I have a math exam soon, i'd appreciate it if someone gave me a step by step solution to simplify these problems:

f(x)=x-1/x^2-6


√-3√-27+√3

____
√4-3+7=12

-
You need to put the directions

For the first one I will speculate that you mean
..........x-1
f(x)=▬▬▬
.........x²-6

and that the directions are
Find the domain.

The domain of this is all reals
.................._
except x=±√6

The second one looks like a simplify


√-3√-27+√3

equals

√81 +√3 = 9+√3

The third does not make sense

____
√4-3+7=12

is a false equation because it simplifies to


1+7=12

Did you make a typo on #3

If any of the others are interpreted wrongly
Post the directions.
