Question

What is the value of
–4.00
–0.25
1.51
2.41

Answer 1

For this case we must resolve the following expression:
`log_ {0.5} (16)`

We have to:

`log_ {a} (x) = \frac {log_ {b} (x)} {log_ {b} (a)}`

The base change rule can be used if a and b are greater than 1 and are not equal to x.

We substitute the values in the base change formula, using
`b = 10`

`\frac {log (16)} {log (0.5)} = - 4`

Answer:

-4

Option A
