Answer:
Explanation:
By definition
log
is the inverse of exponentiation and vice versa for any base
b
. That is:
log
b
(
b
x
)
=
x
for all Real values of
x
b
log
b
x
=
x
for all
x
>
0
The change of base formula tells us that for any
a
,
b
,
c
>
0
with
a
≠
1
and
c
≠
1
:
log
a
b
=
log
c
b
log
c
a
So we find:
log
27
(
1
3
)
=
log
3
(
1
3
)
log
3
27
=
log
3
3
−
1
log
3
3

=
−
