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

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 :

Solve the equation log_(((2+x)/10))7=log_((2/(x+1)))7 .

Solve the equation log_(((2+x)/10))7=log_((2/(x+1)))7 .

Solve the equation log_(((2+x)/10))7=log_((2/(x+1)))7 .

Solve the equation log_(((2+x)/10))7=log_((2/(x+1)))7 .

Solve the equation log_(((2+x)/10))7=log_((2/(x+1)))7 .

3(log_(7)x+log_(x)7)=10
