Question

x-4=log3 243

Answer 1

\[x-4=\log_{3} 243\]
\[3^{(x-4)}=243\]
\[(x-4)\times \ln 3=\ln 243\]
\[x-4=\ln 243/\ln 3\]
Do you follow?

Answer 2

no

Answer 3

What step is troubling you?

Answer 4

everything

Answer 5

If (x-4) is the log to base 3 of 243 then 3 raised to the power of (x-4) must equal 243. This follows from the basic definition of a logarithm.

Answer 6

To finish off
\[x-4=(\ln 243)/\ln 3=5\]
x - 4 = 5
x = 9

Answer 7

\[x-4=\log3 (243) \rightarrow x=\log 3(243)+4\log 3(3). \]

Answer 8

\[since \log 3(3)=1. \]

Answer 9

\[Now,We see\]

Answer 10

\[\log 3(243) +\log 3(3)^4 \]

Answer 11

\[\log 3(243)+\log 3(81)\]

Answer 12

\[\log 3(243*81)=\log 3(19683) \]

Answer 13

\[\log 3(3^6) \]

Answer 14

\[6\log 3(3)= \]

Answer 15

\[6.\]
