Log and Antilog
solve [logap(log(a/p)]/[logpa(log(p/a))] where logap is log base a p
Read Solution (Total 9)
-
- ans will be -logap
- 9 years agoHelpfull: Yes(6) No(0)
- since logap=loga+logp=logpa ,log(a/p)=loga-logp and log(p/a)=logp-loga;
put the value in the given equation
we get
[(loga+logp)(loga-logp)]/[(logp+loga)(logp-loga)]
which is equal to -1. - 9 years agoHelpfull: Yes(3) No(8)
- Ans:(-logap)
- 9 years agoHelpfull: Yes(2) No(0)
- z= [log(base ap)(log(a/p)]/[log(base ap)(log(p/a))]
=> z= [log(base ap)(log(ap^-1))]/[log(base ap)(log(a^-1p))]
=> z= -1[log(base ap)(log(ap))] / -1[log(base ap)(log(ap))]
=> z= -1/-1=1 ...ans - 9 years agoHelpfull: Yes(2) No(1)
- ans is -1 for sure
- 9 years agoHelpfull: Yes(1) No(1)
- answer will be -1
- 9 years agoHelpfull: Yes(0) No(1)
- Can you please explain the answer
- 9 years agoHelpfull: Yes(0) No(0)
- Log base a p can be written as logp/loga (both having base 10)
Hence the ans is 1 - 9 years agoHelpfull: Yes(0) No(2)
- [(loga+logp)(loga-logp)]/[(logp+loga)(logp-loga)]
taking minus common
(-)[(loga+logp)(loga-logp)]/[(logp+loga)(loga-logp)]
we get -1
so ans will be
-1
