on a à+1/à = 7 calculé à^2+1/à^2
Would u please share your idea to prove below statement? a/b=c/d= (a+c) / (b+d) If a,b,c and are non zero integer. I think we can utilize bar model.
Can someone explain the question to me? I don't understand where they said that the balls were equally shared but box d is has the total of box a , b and c... I just tried my luck to do this question... Thx :)
