X and Y together can do a work in \(2\dfrac{2}{5}\) days. Y and Z together can do the same work in 3 days. X and Z together can do the same work in 4 days. The time taken by X, Y and Z together to do the same work is:
If \(x - \dfrac{1}{2x} = 4\) , then the value of \(8x^{3} - \dfrac{1}{x^{3}}\) will be:
If \(x^{4} + \dfrac{16}{x^{4}} = 27217\), x > 0, then the value of \(x + \dfrac{2}{x}\) is:
The area of a circle that is inscribed in a square of area \(17\dfrac{9}{11}\,\text{cm}^{2}\) is:
