Question

How do you use the Change of Base Formula and a calculator to evaluate the logarithm `log_5 10`?

Answer 1

1.43

Explanation:

`log_ab = (log_cb)/(log_ca)`

So with the logarithm `log_5 10` where a=5 and b=10

We can write it as using the change of base formula,

`log_5 10 =(log_10 10)/(log_10 5) = 1/log_10 5 = 1.43`
