not really, i'm kind of having trouble with log

Answer 3

is it \(18 = 6^x+5\)
or
\(\large 18 = 6^{x+5}\)
??

Answer 4

\[18=6^{x+5}\]

Answer 5

ok, you can take log on both sides from the very 1st step,
left will be log 18
you need to simplify the right side, \(\log 6^{x+5}\)
by the property of log that \(\log a^b=b\log a\)
try ?

Answer 6

log18= x+5 log 6

Answer 7

now divide both side by log 6

Answer 8

i got X= log 3-5

Answer 9

log 3?how?

Answer 10

log 18/log 6 is not equal to log 3 !

Answer 11

so your answer is x=(log 18/log 6) - 5

Answer 12

oh okay got it. thank you for your help!

Answer 13

my pleasure...
