If the sum of the first 20 terms of the series
`log_((7^(1//2)))x + log_((7^(1//3))) x + log_((7^(1//4)))x + ....` is 460 , then x is equal to :

If sum of the first 21 terms of series log _((1)/( 9 ^(2))) x + log _((1)/(9 ^(3))) x + log _((1)/( 9 ^(4))) x + ..., where x gt 0 is 504, then x is equal to :

If log_7^(1/2) x+ log_7^(1/3)x+ log_7^(1/4)x +.....20 times = 460 than x=?
