Which number is a perfect cube? 9 18 27 36

27 is the perfect cube in your list

Hi!

A number that has a perfect cube is a number that can be solved like this

x³ = n

Let's test all these numbers.

9

Does 9 have a perfect cube? Let's factorize it to find out.

9/3 = 3

3/3 = 1

3 * 3 is 9's factorization. That is not a perfect cube.

18

Do the same thing.

18/2 = 9

9/3 = 3

3/3 = 1

2 * 3 * 3 is 18's factorization. It is not a perfect cube.

27

27/3 = 9

9/3 = 3

3/3 = 1

3 * 3 * 3 is 27's factorization. It is a perfect cube!

3³ = 27

Hope this helps! :)

step-by-step explanation:

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.
