When a number is multiplied by itself three times, then the resultant number is called a perfect cube. It is also a number with an exact cube root.
Out of the given options, and are perfect cubes.
= (2's are multiplied and powers are added)
= (3's are multiplied and powers are added)
The monomials that are perfect cubes out of the options given are: B. 8x^12, and C. 27x9.
A perfect cube is a number that can give you a precise cube root, i.e. a³ = a × a × a = ∛a³ = a.
27x^9 can be expressed as: ∛(27x^9) = 3x³
8x^12 can be expressed as: ∛(8x^12) = 2x^4
Therefore, the perfect cubes are: B. 8x^12, and C. 27x9.
