Question

Which logarithmic equation is equivalent to the exponential equation below
5^c=125

log5 125=c

logc 125=5

log5c=125

log125c=5

Answer 1

A xD

Answer 2

@MarrBear STOP HELPING ME!!!

Answer 3

Aw :c

Answer 4

\(\LARGE\color{black}{ \log_AB^C ~~~~~⇒~~~~~A^C=B}\)

Answer 5

by definition

if a^b = c

then loga c = b

Answer 6

@MarrBear LOL jk hahahha

Answer 7

\(\Large\color{blue}{ \rm \log_AB^C ~~~~~⇒~~~~~A^C=B}\) is also a proof for why there is no negative log, unless the base is negative, and the log is odd.

Answer 8

the important thing to remember is that the logarithm is the exponent to which the base is taken

Answer 9

@cwrw238 @SolomonZelman @MarrBear Thank you all for the quick help I am extremely bad at logarithms

Answer 10

Clarke, we can fix that if you want to :)

You welcome !

Answer 11

Remember the formula i gave you xD. its very simple

Answer 12

@SolomonZelman @MarrBear I understand it is as easy as just plugging the logs into the formula but some dont fit, Like this one "log784=a"

Answer 13

If it doesnt have a Base, the base is ALWAYS 10.

Answer 14

@MarrBear i'll remember that

Answer 15

So it would be 784= 10^a c:

Answer 16

@MarrBear so log400=a would be 10^a=400

Answer 17

Exactly! (:

Answer 18

@MarrBear its so simple... -_-
