Question

How do I write an algebraic expression using the sieve of eratosthenes?

Answer 1

i dont htink the seive is algebraic, moreso its more of an algorithm

Answer 2

you circle the lowest prime; and cross out all the number above it that it is a factor of; then the next number unscratchedout number on the list goes thru the same process

Answer 3

my daughter has homework that says she need to write an algebraic expression using the sieve of eratosthenes. Example she is to cross out every multiple of two and then write an algebraic expression for the numbers she crossed out

Answer 4

every multiple of 2 is what: 2*n

Answer 5

if there was an example to go by it be helpful; this does seem a bit vague to me tho

Answer 6

i don't know. she has to use a number board 1-100. i was thinking 2x?

Answer 7

2n; such that n>1 maybe

Answer 8

the variable itself can have any name it wants; the name doesnt change it

2x is fine

Answer 9

but you have to define what xs you use since you dont wanna cross out 2*1

Answer 10

here is an example of the problem. Circle the number 2 wit yellow. cross out evry multiple of 2 with yellow. Write an algebraic expression for the numbers you crossed out.

Answer 11

"n"umber

2n such that n is a natural number greater than 1

Answer 12

and less than 51 i spose :)

Answer 13

ok. I have no clue. thanks.

Answer 14

\[2n\ \{n|n\in N: (1,51)\}\]

you would have to define a domain of the ns you use so that you exclude 2*1 itself as a crossed out. and since you only go up to 2*50 max you can say you stopped with natrual numbers less than 51

other than that .... im at a loss as well
