Answer 2

Answer:

the answer is zero

Step-by-step explanation:

2^a=3^b=12^c = k     --------->   (assuming)

so,

2^a = k

2 = k^1/a  

similarly we get,

k^1/a = k^1/b = k^1/c

so think about bringing the nos. 2 and 3 being equalent to 12 then we get,

2^2*3 = 12

in terms of k, we get

(k^1/a)^2 * (k^1/b) = k^1/c

k^(2/a+1/b) = k(1/c)   -------->  (taking k in common)

after cancelling k we get,

2/a + 1/b = 1/c

so finally we get,

0 = 1/c-1/b-2/a
