here is you answer. I hope it will help you
Step-by-step explanation:
Answer:
I found
−
2
if the log is in base
10
.
Explanation:
I would imagine the log base being
10
so we write:
log
10
(
0.01
)
=
x
we use the definition of log to write:
10
x
=
0.01
but
0.01
can be written as:
10
−
2
(corresponding to
1
100
).
so we get:
10
x
=
10
−
2
to be equal we need that:
x
=
−
2
so:
log
10
(
0.01
)
=
−
2
