Answer 2

The factorisation of $27a^3b^3-45a^4b^2$ $=9a^3b^2(3b-5a)$

Step-by-step explanation:

We have,

$27a^3b^3-45a^4b^2$

To find, the value of $27a^3b^3-45a^4b^2=?$

∴ $27a^3b^3-45a^4b^2$

$=(9\times 3)a^3b^3-(9\times 5)a^4b^2$

$=9(3a^3b^3-5a^4b^2)$

$=9a^3(3b^3-5ab^2)$

$=9a^3b^2(3b-5a)$

The value of $27a^3b^3-45a^4b^2$$=9a^3b^2(3b-5a)$

Hence, the factorisation of $27a^3b^3-45a^4b^2$ $=9a^3b^2(3b-5a)$
