Answer:

Conjecture : 2xy / ( x + y ) ≤ √xy

Step-by-step explanation:

Harmonic mean of x and y = 2xy/( x + y )

Formulate a conjecture about their relative sizes

we will achieve this by computing harmonic and geometric means

Geometric mean = √xy

harmonic mean = 2xy/( x + y )

Conjecture : 2xy / ( x + y ) ≤ √xy

attached below is the proof
