Hi i am doing a buiolding surveying degree and have come across this log question that im stuck on as i havnt come across them before. If someone could help me out that would be great. Iv got to work out T in each case.
53=10 log (1/T)
log 1/T = 5.3
1/T=
25=10 log (1/T)
log 1/T = 2.5
1/T=
20=10 log (1/T)
log 1/T = 2
1/T=
Thanks for any help

53=10 log (1/T)
log 1/T = 5.3
10^5.3=1/T
199526.2315=1/T
T=5.011872336 x10^-6
25=10 log (1/T)
log 1/T = 2.5
10^2.5=1/T
316.227766=1/T
T=0.0031622777
20=10 log (1/T)
log 1/T = 2
100=1/T
T=0.01
or of the numerators meant bases:
53=10 log (1/T)
log 1/T = 5.3
log T/Log 1=5.3
log 1 = 0;denominators can't be zero(same for all)
or if the denominators meant bases:
53=10 log (1/T)
log 1/T = 5.3
log 1/log T = 5.3
log 1=0
0/log T=5.3
there is no answer in this case
