Given that 2 ^ x = 3 ^ y = 5 ^ Z and X, y, Z are positive numbers, the size relation of 2x, 3Y, 5Y is?

Given that 2 ^ x = 3 ^ y = 5 ^ Z and X, y, Z are positive numbers, the size relation of 2x, 3Y, 5Y is?

It's 2x, 3Y, 5Z, wrong number? LG2 ^ x = Lg3 ^ y = lg5 ^ Z, X * LG2 = y * Lg3 = Z * lg5, x = ylg3 / LG2, z = y * Lg3 / lg5, so 2x = 2ylg3 / LG2, 5Z = 5Y * Lg3 / lg5, compare the sizes of 2lg3 / LG2, 5lg3 / lg5 and 3. 2lg3 / LG2 = log2 (9) and 3 = log2 (8) obviously, the former is bigger, so 2x is greater than 3Y; 5lg3 /
