•Given:-

• 2x - 3y = 10
• xy = 16

•To find:-

• Value of 8x³ - 27y³.

•Solution:-

Formula Use :-

a³ - b³ = (a-b)³+3ab(a-b)

Taking 8x³ - 27y³.

$\sf{8x^3-27y^3}$

$\sf{\implies{(2x)^3-(3y)^3}}$

$\sf{\implies{(2x-3y)^3+3\times\:2x\times\:3y(2x-3y)}}$

$\sf{\green{Putting\: the\: values\: of\:(2x-3y)=10\:and\:xy = 16}}$

$\sf{\implies{(10)^3+18\times\:16(10)}}$

$\sf{\implies{2980(Answer)}}$
