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
