Question

find the value of log400 ????​

Answer 1

Step-by-step explanation:

logb(x / y) = logb(x) - logb(y)

Note that division inside the log can be turned into subtraction outside the log, and vice versa

In our case, we will turn the subtraction outside the log into division inside the log.

So, as 400/4=100

We end up with log(100) as our answer

The base 10 log of 100 is 2

Answer 2

Answer:

2 log20

2 (log 2+log 10)

2(o.1+1)

2.2
