Use the identity below to complete the tasks: a3 − b3 = (a − b)(a2 + ab + b2) when using the identity for the sum of two cubes to factor 125q6 − r6s3. what is a? what is b?

a = 5q²

b = r²s

Step-by-step explanation:

The given identity is

we have to use this identity to factor of two cubes given as " alt="125q^{6}-r^{6}s^{3}=(5q^{2})^{3}-(r^{2}s)^{3}" />" />

As this expression is in the form of a³- b³

Here a is 5q² and b is r²s.

b

step-by-step explanation:

the word superfluous means unnecessary
