Sorry i am being dumb, in part a of the Q you had to simplify the nested radical so there is no working to be done. Its the initial nested radical. sorry to waste your time.View attachment 21722
I can simpify a nested equation but how does one work backwards?
how did they go from 1-square in the brackets to nested radical in the numerator for instance.Which part do you not understand?
give me some time to think and show you some workings. sorry i forget how hard it is for you to read my mind. ?Which part do you not understand?
I have trouble reading my own mind. Come to think of it I can probably read your mind better than my mind.give me some time to think and show you some workings. sorry i forget how hard it is for you to read my mind. ?

give me a min please. Sorry to be so slow. Its too hot to even think straight today.Can you square what is inside the parenthesis? Then subtract it from 1?
I don't get there either. I get \(\displaystyle \frac{\sqrt{3}}{2}\)how did they go from 1-square in the brackets to nested radical in the numerator for instance.

Yes I dont understand how they derived the radical in this bit. I dont get it.
so i was right, that step with radicals is just a errorPlease study this attached file.
