Now its addition logx+log7=39

is it really 39 cross check it it must be 49

Nope it says 39.

rule is logx +logy means log (x * y)

so 7x=39?

logx+log7=39 log7x=39 7x=10^39 x=1.43X10^38

turning test don't give answer straight a way first explain the rules it will help him to understand the things in abetter way

Yeah im lost by the x=1.43X10^38

yeah but here log7x=39

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

the answer would be like. 5.55

now if we will take antilog we will get 7x = antilog (39)

I dont know what antilog is ?

neither do I LOL!

it is inverse of log!!

well I figure as much...

just never heard of it before and don't see why you need it

because u have log only on one side not on both the sides

Alright. Thank you again! :)

hey friend here if ur answer is 5.5 then ur question must be logx + log 7 = log 39
