Read Solution (Total 4)
-
- x=4.........
( log (0.1)/log (x) )= -1/3 .........solve you will get ans - 10 years agoHelpfull: Yes(0) No(3)
- We know that log b (a) = log e (a)/log e (b).
=> loge (0.1)/loge (x) = -1/3.
Apply e log on num and den
=> e^loge (0.1) /e^loge (x) = (-1/3)
=> 0.1/x = -1/3
=>x = -0.3 - 10 years agoHelpfull: Yes(0) No(1)
- x=1000
solve this -
( log (0.1)/log (x) )= -1/3 - 10 years agoHelpfull: Yes(0) No(0)
- Ans: 1000
Previously I have taken e log , but take natural log on top and bottom.
=> Log 10 (0.1)/log 10 (x)= -1/3
=>-1/log 10 (x) = -1/3 (log 10 (0.1) = -1 log 10 (10) = -1)
=>log 10 (x) = 3
=> x= 10^3
=1000. - 10 years agoHelpfull: Yes(0) No(0)
