Question : If $2x+3y = 4$ and $4x^{2}+9y^{2}= 64$, then what is the value of $8x^{3}+27y^{3}$:
Option 1: 253
Option 2: 235
Option 3: 352
Option 4: 325
Correct Answer: 352
Solution : Given: $2x+3y=4$ and $4x^2+9x^2=64$ To find: $8x^3+27y^3$ Now, $2x+3y=4$ Squaring both sides, we get: ⇒ $4x^2+9y^2+12xy=16$ Putting the values, we get: ⇒ $64+12xy=16$ ⇒ $12xy=-48$ ⇒ $xy=-4$ Now again, $2x+3y=4$ Cubing both sides, we get: ⇒ $8x^3+27y^3+3×2x×3y(2x+3y)=64$ Putting the values, we get: ⇒ $8x^3+27y^3+18×(-4)×4=64$ $\therefore8x^3+27y^3=64+288=
