Contact Pro Premium Expert Support ».  Hi I'm Piyush I'm obsessed by Maths It's my drug And here's your solution Solution 2 x = 3 y = (12) z = k 2 x = k, 3 y = k, (12) z = k 2 = k 1/x, 3 = k 1/y, 12 = k 1/z 12 = 2 2 x 3 k1/z = (k 1/x) 2 x k 1/y k1/z = k 1/x x 2 x k 1/ Since, (a m) n = a mn k1/z = k 2/x x k 1/y k1/z = k 2/x1/y Since, am x an = amn 1/z = 2/x 1/y, Since, bases are same ie base = k.  We know that x = 5 and y = 12, so we can use the original equation to determine that z = 13 We can plug in all the values that we now know 2(13) dz dt = 2(5)2 2(12)3 dz dt = 46 13 Note that z could also equal −13, but I am assuming that the physical restrictions behind this problem would not allow such an answer.

Answer (1 of 7) Let 2^x = 3^y = 12^z = r Then 2 = r^{1/x}, 3 = r^{1/y}, and 12 = r^{1/z} Since 12 = 2^2 \cdot 3, r^{1/z} = r^{2/x} \cdot r^{1/y}, or \dfrac{2}{x} = \dfrac{1}{z} \dfrac{1}{y} = \dfrac{yz}{yz} Thus x = \dfrac{2yz}{yz} \blacksquare.
