task/29732072 Упростить выражение ( (a -b) / (∛a -∛b) +∛ab ) : (∛a +∛b)²
( (a -b)/(∛a -∛b) +∛ab ) : (∛a +∛b)²=( ( (∛a)³-(∛b)³ ) / (∛a -∛b) +∛ab ) :(∛a +∛b) =
( (∛a -∛b) (∛a² +∛ab +∛b² ) / (∛a -∛b) +∛ab ) : (∛a +∛b) =
( ∛a² +∛ab +∛b² +∛ab ) : (∛a +∛b) = ( ∛a² +2∛a*∛b +∛b²) ) : ( ∛a +∛b )² =
( ∛a +∛b )² : ( ∛a +∛b )² = 1 .
