maths question..............................................

If 9(1/h) = 11(1/k) = 99 , where h and k are not equal to 0 , determine the value of h+k without finding the values of h and k.

thanks for your help!

更新:

It should be 9^(1/h) = 11^(1/k) = 99

    9(1/h)=99

    99^h = 9 -(1)

    11(1/k) = 99

    99^k = 11 -(2)

    (1)+(2): 99^(h+k) = 99

    h+k = 1
