What value should come in the place of question mark (?) in the following questions ?
$$\frac{15}{31}\div\frac{90}{186}\times\frac{729}{9}=(?)^{2}$$
Expression : $$\frac{15}{31}\div\frac{90}{186}\times\frac{729}{9}=(?)^{2}$$
=> $$?^2 = \frac{15}{31} \times \frac{186}{90} \times 81$$
=> $$?^2 = 1 \times 81 = 81$$
=> $$? = \sqrt{81} = \pm9$$
