Confirmation for 4u q and how to do part b (1 Viewer)

[lmao1010]

Can someone verify if I'm doing part a of 16 correctly or not? AND also how do i approach part i and ii

 

[=)(=]

someone correct me if i am wrong but part a is fine you could get a common denominator on the LHS then subtract the RHS and the also find a common denominator and hence combining that into 1 fraction, you should get (x-y)^2/(xy(x+y))>=0 which is true since x and y are real positive numbers part ii can be solved the same way

Most steps are correct however I find this to be cleaner.




That is what I would do if I were you @lmao1010

Ah ok thanks m8 yep that does seem cleaner

Thx

You mean part ii

 

[lmao1010]

You mean part ii

yh i think we do part ii using that identity

 

[5uckerberg]

yh i think we do part ii using that identity

What is the full question from part ii?
