Answer 1

Answer:

a+1a= then a3 +1

Step-by-step explanation:

a+1a= then a3 +1=a+2a or a3+1

Answer 2

Answer:

Given a+1/a=1

Given a+1/a=1multiply with a^2 both sides

Given a+1/a=1multiply with a^2 both sidesa^3+a=a^2_______(1)

Given a+1/a=1multiply with a^2 both sidesa^3+a=a^2_______(1)=>a(a^2+1)=a^2

Given a+1/a=1multiply with a^2 both sidesa^3+a=a^2_______(1)=>a(a^2+1)=a^2=>a^2=a-1;

Given a+1/a=1multiply with a^2 both sidesa^3+a=a^2_______(1)=>a(a^2+1)=a^2=>a^2=a-1;now from 1, a^3=a^2-1=>a^3+a=a-1=>a^3=-1
