Question

bil triven thal, ( x-2 y=8 ) ( 8 x y=6 ) then find of ( x^{3}-8 y^{3}= )
( sin (R)-1+2 y=8 )
Cube on both side. ( (x-2 y)^{3}=(8)^{3} )
( 7 x^{3}-8 y^{3}-3 x y(x-2 y)=8 times 8 times 8 )
( left.Rightarrow quad x^{3}-8 y^{3}=512-3 times 6 times 18right) )
( Rightarrow x^{3}-8 y^{3}=512-144 )
( Rightarrow x^{3}-8 y^{3}=368 )
