Question

factorise it
step by step ans​

Answer 1

Answer:

factorie

125x³- 64y³

=(5x)³-(4y)³

=(5x-4y) (25x²+20xy+16y²)

$\mathfrak \red{by \: using \: this \: formula}$

a³-b³=(a-b)(a²+ab+b²)

Answer 2

$125x {}^{3} - 64y {}^{3} \\ (5x) {}^{3} - (4y ){}^{3}$

now factorise on a3-b3 you will get tha answer
