помогите пожалуста срочнооо​

Ответ:

Пошаговое объяснение:

1) 6/(5 -1/(2 -1/(1 -1/3)))=6/(5 -1/(2 -1/(3/3 -1/3)))=6/(5 -1/(2 -1/(2/3)))=6/(5 -1/(2 -3/2))=6/(5 -1/(4/2 -3/2))=6/(5 -1(1/2))=6/(5-2)=6/3=2

2) 4/(3 -1/(2- 1/(1- 1/5)))=4/(3 -1/(2- 1/(5/5 -1/5)))=4/(3 -1/(2- 1/(4/5)))=4/(3 -1/(2- 5/4))=4/(3 -1/(8/4 -5/4))=4/(3 -1/(3/4))=4/(3 -4/3)=4/(9/3 -4/3)=4/(5/3)=(4·3)/5=12/5=2 2/5=2,4
