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 t
saveliy_v [14]

Answer:

a=5q^ {2}

b=r^{2}s

Step-by-step explanation:

Here 125q^{6} is like the a^{3} in the general formula.

So we can write 125q^{6} as:

(5q^ {2} )^{3}

We can also write r^{6} s^{3} as:

(r^{2}s)^{2}

Therefore:

a³=(5q^ {2} )^{3}

b²=(r^{2}s)^{2}
