is it really 39 cross check it it must be 49
OpenStudy (anonymous):
Nope it says 39.
OpenStudy (anonymous):
rule is logx +logy means log (x * y)
OpenStudy (anonymous):
so 7x=39?
OpenStudy (turingtest):
logx+log7=39
log7x=39
7x=10^39
x=1.43X10^38
Still Need Help?

turning test don't give answer straight a way first explain the rules it will help him to understand the things in abetter way
OpenStudy (anonymous):
Yeah im lost by the x=1.43X10^38
OpenStudy (anonymous):
yeah but here log7x=39
OpenStudy (turingtest):
you already gave the rules sheg, otherwise I would have
My anser is in scientific notation since the number is so large (assuming a base 10 log)
log7x=39
7x=10^39
x=(10^39)/7=1.43(10^38)
I just wrote the answer inscientic notation because the number is so large
OpenStudy (anonymous):
the answer would be like. 5.55

now if we will take antilog
we will get
7x = antilog (39)
OpenStudy (anonymous):
I dont know what antilog is ?
OpenStudy (turingtest):
neither do I LOL!
OpenStudy (anonymous):
it is inverse of log!!
OpenStudy (turingtest):
well I figure as much...

just never heard of it before and don't see why you need it
OpenStudy (anonymous):
because u have log only on one side not on both the sides
OpenStudy (anonymous):
Alright. Thank you again! :)
OpenStudy (anonymous):
hey friend here if ur answer is 5.5 then ur question must be
logx + log 7 = log 39
