Answer 1

Answer:

-3

Step-by-step explanation:

It is useful to remind ourselves of what a logarithm is. They can use any base. The bases that are in widespread use are logs to the base

10 , and logs to the base e . When we write log a b , we are asking to what power do we raise the base a to get b . So if log a b=c, then ac = b

. It would be worth your while to get your head round this.

So, in effect, the question asks to what power must we raise the base 10 to get 10 power -3 (because, as you realize, 0.001=10 power−3).

its the answer...
