If u,v>0 and u^2=v^2 means that u=v. Therefore the ans is always No.

A
am confused, since option 1 answers that u=v, then obviously u cant be > v, so the answer is answered from option 1 itself independently

v

viplav .. u = -1 , v = 1 , u~2 = v~2 , but u 0 is necessary

C

u=-1, v=1 , then u^2 = v^2, but u,v >0, so u=v=1
Hence u not equal to v

u^2=v^2 is impossible if u>v
so ans cannot be determined

Nidhi,

u^2 = v^2 is possible even if u>v, For example (u,v)= (1,-1),
(2,-2) ….
I hope it’s clear now..:)
