Come si semplifica (sqrt (3) – 1) / (1 + sqrt (3))?
Come si semplifica (sqrt (3) – 1) / (1 + sqrt (3))? Risposta: #2-sqrt(3)# Spiegazione: #(sqrt(3)-1)/(1+sqrt(3)#=#(-1+sqrt(3))/(1+sqrt(3))# = #(-1+sqrt(3))/(1+sqrt(3)). (1-sqrt(3))/(1-sqrt(3))# = #(-1+2sqrt(3)-3)/(1-3)#= #(2sqrt(3)-4)/(-2)# = #2-sqrt(3)#
