Question

C = {x : x is perfect cube, 27 < x < 216}

Answer 1

Answer:

C = { 64 , 125 }

Step-by-step explanation:

Given:  Set C = { x : x is perfect cube and 27 < x < 216 }

To find: Elements of set c and write in roaster form.

Element of Set C are perfect cube between 27 and 216.

A perfect cube is the result of multiplying a number three times by itself.

Here, 27 is perfect cube with cube root = 3 and 216 is also perfect cube with cube root = 6.

So, we have only number 4 and 5 between 3 & 6.

So, Set C contain Cubes of 4 and 5 that is 64 and 125.

Therefore, C = { 64 , 125 }

Answer 2

Answer:

C = { 64 , 125 }

Step-by-step explanation:

We given a set builder form of Set C.

We need to find roaster form of set or elements of set C.

Element of Set C are perfect cube between 27 and 216.

Perfect cube is a number whose cube root is a integer or we can say it is a number which obtained by multiplying an integers 3 times.

Here, 27 is perfect cube with cube root = 3 and 216 is also perfect cube with cube root = 6.

So, we have only number 4 and 5 between 3 & 6.

So, Set C contain Cubes of 4 and 5 that is 64 and 125.
