Question

please answer in detail

Answer 1

(1) would be the answer!!

Since if root (a) be similar to root (c) and root (b)
Then root (a) would not be equal to each of root (b) and (c) of it rather be double and if root (a) be similar to (b) then root (c) would mean to be 0

Thus I hope ur answer is (1)

Answer 2

√a=√b+√c
on taking square on both sides

a=b+c+2√bc
a-b-c=2√bc
now as RHS will be always positive LHS will also be positive.
thus
a-b-c>=0
a>=b+c

therefore ans should be (1)
