I am uncertain whether one is allowed to have repeated elements of a sequence An in a subsequence Bn. If for instance the first few terms of An are:

An = 0, 1, 2, 3, 4, 5, 6, 7...

Is this a possible subsequence:

Bn= 0, 0, 0, 0, 0, 1, 1, 2...

I know elements have to stay ordered, but I am not certain of whether they may be used more than once consecutively. I ask this because as a challenge we were asked to find a sequence from which one could find subseqences that would converge to a) Every rational and b) Every irrational. If repeated elements are allowed then the question could be very simply answered, if not then it is more difficult.

Hey, I don't have a single Sceintific Calculator, just regular characters...
In order to do these sums I need a specific button... that is the Xy button...
Here are the questions... please help, I wouldnt normally ask for help but I really need it, no rescources to do it myself...

(1.012)9 (the 9 is a tiny one that sits raised up above the rest, if you know what I meen)

(1.035)8 (same with this 8)


Basically, the formula of button to press is this...
Press 1.035 > Xy > 9 > =
and the same with the other...
Thankyou for you help :) I appreciate it in advance...

use synthetic division:

6x²+ 11x^5-28x^4 - 39x³ +4 6x^2 +28x - 24 ÷ 2x^3 - x^2 – 7x + 6=

8x^5 – 14x^4y - 13x^3 y + 16x^2 y + 5xy^4 – 2y^5 ÷ 4x^2 + 3xy – y^2 =

2x^6 – 3x^4 – x^2 + 2x – 3 ÷ x^3 – 2x^2 + x – 3=

3x^5 – 2x^3 + x – 1 ÷ 2x + 1=


well.. i don't know how to do it...can smbody pls.. explain to me and pls. teach me how to solve this...

thnx in advance..
