Question

factorise the following ...... any one ques can do ..... plz give step by step explanation...​

Answer 1

Answer:

8(i) they are cubes, so to factorise, take cube roots.

$\sqrt[3]{27} = 3$

$\sqrt[3]{8} = 2$

do the same for the variable too.

(3m+2x)^3

(ii)

$\sqrt[3]{125} = 5 and \: \sqrt[3]{64} = 4$

so again do the same for the variables too

(5s-4y)^3

(iii) (1/5y-6/x)^3

(iv) (x/2+2/y)^3
