Which is a difference of cubes?<br><br> x6 – 27<br> x15 – 36<br> x16 – 64<br> x5 – 125
shutvik [7]

Answer:

The correct option is 1.

Step-by-step explanation:

The difference of cubes is defined as

a^3-b^3=(a-b)(a^2+ab+b^2)

The given expression is

x^6-27

It can be written as

x^6-3^3

Using the property of exponent, the above expression can be written as

(x^2)^3-3^3                [\because (x^m)^n=x^{mn}]

This is a difference of cubes.

Therefore the correct option is 1.
