Question 135611: I'm having a little trouble with this question. I can't find anything in our book that looks anything like it. The instructions are: "solve each equation, inequality or system of equations"
square root x-1=x-1
I tried this
x-1=(x-1)^2 Remove the square root form the left side and square the right.
-x^2+x-1+1^2=0 Set the equation to zero and cancell -1 and +1^2
x^2-x=0
There doesn't seem to be a solution.
Am I even approaching this correctly?

Question 135770: I would appreciate some help on these adding radical problems,but of course I don't have the square root sign on the computer, so I'll try to explain the best way I can.Thank you for your patients in advance.
1)3 then square root sign 45 + 7 then square root sign 20
2)3 then cubed in the square sign then 16 under the square sign + cubed then 54 under the square root sign.

I hope I explained these two questions where someone could understand them.
Thanks again LH

Question 135825: hey i am taking algebra 1b this semester and i am having trouble understanding my homework. at the top of my worksheet it says simplifying radical expressions.
all my problems are fractions. i do not have a square root button so i'll try my best to explain one of the problems by typing "square root sign" since i have no square root sign. thankyou for your support and if this is to hard to understand without the square root button i understand.
"square root sign"75/"square root sign"3

this is a fraction of 75/3 with the square root sign over each number.
