Question

Now its addition logx+log7=39

Answer 1

is it really 39 cross check it it must be 49

Answer 2

Nope it says 39.

Answer 3

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

Answer 4

so 7x=39?

Answer 5

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

Answer 6

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

Answer 7

Yeah im lost by the x=1.43X10^38

Answer 8

yeah but here log7x=39

Answer 9

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

Answer 10

the answer would be like. 5.55

Answer 11

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

Answer 12

I dont know what antilog is ?

Answer 13

neither do I LOL!

Answer 14

it is inverse of log!!

Answer 15

well I figure as much...

Answer 16

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

Answer 17

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

Answer 18

Alright. Thank you again! :)

Answer 19

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