यदि `x(x-3)=-1` है तो `x^(3)(x^(3)-18)` का मान ज्ञात करें।A. -1B. 2C. 1D. 0 |
|
Answer» Correct Answer - A `x(x-3)=-1` `implies (x-3)=(-1)/x` Taking cube on both sides `implies (x-3)^(3)=((-1)/x)^(3)` `implies x^(3)-27-9xx(x-3)=(-1)/(x^(3))` `implies x^(3)-27-9xx-1=(-1)/(x^(3))` `implies x^(3)-27+9=(-1)/(x^(3))` `implies x^(3)-18=(-1)/(x^(3))` `implies x^(3)(x^(3)-18)=-1` |
