Comparison - Kevyn Yong (22)


Comparison
a) 2n and 2+n
- They will never be equal unless n=2- 2n is 2*n while 2+n is 2+n.b) 2n and n^2- They will be equal only when n=2- 2n is 2*n while n^2 is n*nc) 2n+2 and 2(n+2)- They will never be equal as 2(n+2) will always be greater than 2n+2 by 2- 2n+2 is (2*n)+2 while 2(n+2) is 2*(n+2)d) 2n^2 and (2n)^2


- (2n)^2 will always be twice the value of 2n^2 unless n=0
- 2n^2 is 2*(n*n) while (2n)^2 is (2*n)*(2*n)
