Hi all ---
For this multiple choice question, I don't know how to compare (a) and (b).
I try ---
or if I sub in L ---
Squaring both sides ---
Because --- squaring this for the 1st and then multiplying by 2 for the 2nd --- and .
1st Question --- But how can I compare the last two inequalities? I don't know what specifically L is?
2nd Question --- How does solution get ?
Thanks a lot ---
