Question
answer asap, i need solutions also
![Encoding of numerical answers: (avoid spaces)
positive x: type as x
negative x: type as -x
fraction a over b: type as a/b or as a whole number with
exact decimal part ex. 0.5 or 12.34
negative fraction a over b: type as -a/b or as a negative of a
whole number w/ exact decimal part ex. -0.5 or -12.34
square root of x: type as sqrt(x) ex. sqrt(2) or as non
perfect nth roots sqrt[n] (x) ex. cube root of 10 as sqrt[3]
(10) or as irrational numbers such as pi or the euler
constant e
negative square root of x: type as -sqrt(x) ex. -sqrt(2) (do
not put a space between the negative sign and the number)
rationalized denominators: instead of 1/sqrt(x)
type sqrt(x)/x
for typing infinity or negative infinity type infty or -infty (type
this if the sequence is divergent but diverges to either
infinity or negative infinity)
if value does not exist or is undefined: type dne
for multiple values enumerate and separate only by
commas, in INCREASING ORDER, with no spaces in
between: ex. for 1 and 2 and negative 3 over 4,
type -2,3/4,1
if you are asked to find a set S, just use the roster method
(list elements in increasing order), without spaces,
{-2,3/4,1}](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fffc34a14-336d-4879-a115-3e436a77b08b%2Fb1292b26-568e-406b-a1ac-39bb303a9aae%2Fi9k8fgc_processed.jpeg&w=3840&q=75)
