Question

15. Factorise
Factorise x^6 - 729​

Answer 1

Answer:

Have a nice day..

Step-by-step explanation:

Here,

we have to factorise x^6-729

now, we know that

$729 = {3}^{6}$

therefore,

${x}^{6} - {3}^{6} = 0$

$or \: \: ( {x}^{3}+ {3}^{3})( {x}^{3} - {3}^{3} ) = 0$

$or \: (x + 3)( {x}^{2} - 3x + 9)(x - 3)( {x}^{2} + 3x + 9) = 0$

so,

this is the required answer...

thanks a lot...
