Answer 1

Answer:

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
