(ay)+2y3,if a= 2 and y= 3
(23)2 + 2(3)3
(5)2 + (6)3
25 + 216
191 either im wrong somewhere or my book doesnt have that answer my choices are 29,43,79,53
I am assuming that by 2(3)3 you mean
2(3)^{3}
you did not follow the order of operation which says exponents before multiplying
that part should then be
2(27)
so your last line is
25 + (54)
= 29

If 2^n>n^2 and n>5, then 2^n+1>(n+1)^2 Proof: Assuming that 2^n>n^2 then I can say that 2*2^2>2*n^2 = 2^n+1>2n^2 If I can show that 2n^2>(n+1)^2 then I will be done by transitivity. So 2n^2>(n+1)^2?
