(B) આપેલ સમીકરણ: $20^{2-3x^2} = (40\sqrt{5})^{3x^2-2}$.અહીં $40\sqrt{5} = 20 	imes 2 	imes \sqrt{5} = 20 	imes \sqrt{20} = 20^{3/2}$ થાય.તેથી,$20^{2-3x^2} = (20^{3/2})^{3x^2-2} = 20^{\frac{3}{2}(3x^2-2)}$.ઘાતાંકોને સરખાવતા:$2-3x^2 = \frac{3}{2}(3x^2-2)$$2-3x^2 = -\frac{3}{2}(2-3x^2)$$(2-3x^2)(1 + \frac{3}{2}) = 0$$2-3x^2 = 0$$3x^2 = 2$$x^2 = \frac{2}{3}$$x = \pm \sqrt{\frac{2}{3}}$.

જો $20^{2-3x^2} = (40\sqrt{5})^{3x^2-2}$ હોય,તો $x$ ની કિંમત શોધો.
