Question

Write the following set in roster form:

B= {x : x = n3 − 2 , n ∈ N and 3 ≤ n ≤ 5 }​

Answer 1

Answer:

B = { 25 , 62 , 123 } is the roster form for B

Answer 2

Answer:

B = {7,10,13}

Step-by-step explanation:

given 3<=n<=5

n=3,4,5

X=n3-2 (put n=3,4,5)

on solving x differently we get 7,10,13 respectively

therefore

B={ 7,10,13}
