Question

Express in roster method:
C= {x:x³-1=0}

Answer 1

Answer:C={+1}

Step-by-step explanation:Let me explain. Well 1 is the only number that can do it

Answer 2

Answer:

The roaster form is

$C={1, (-1)^{\frac{2}{3}}, -\sqrt[3]{-1} }$  

Step-by-step explanation:

Given the set C in set builder form

C= {x : x³-1 = 0}

we have to write set C in roaster form.

In set theory, roster form is a group of members of set is placed between brackets, with the individual elements separated by commas.

$C=\{x:x^3-1=0\}$

$C=\{x:x^3=1\}$

$C=\{x:x=\sqrt[3]{1}\}$  

$C=\{1, (-1)^{\frac{2}{3}}, -\sqrt[3]{-1} \}$
