the answer:
the full question is as follow 
What is the value of log0.5 ^16

first of all, we should know some logarithm property
for example:
log a^p = p log a, for all a a positive number, an p a real number

therefore, 
log0.5 ^16 = 16log0.5, and log0.5 = -0.69, 
finally
log0.5 ^16 = 16log0.5=16*(-0.69)= -11


Answer:

You mean ?

[tex]log_0_._5 (16) =-4[/tex]

or

You mean?

[tex]log(0.5)^{16}=-11.09035489[/tex]

Step-by-step explanation:

If you trying to solve:

[tex]log_0_._5(16)[/tex]

Then use the definition of the base of a log which is:

[tex]log_xy=z\Rightarrow x^z=y[/tex]

[tex]0.5^z=16[/tex]  

Rewrite 0.5 as:

[tex]0.5=\frac{1}{2}[/tex]

As you may know:

[tex]2^4=16[/tex]

[tex]then\\\\z=-4[/tex]

Let's use the negative exponent propierty in order to verify the result:

[tex]a^{-n}=\frac{1}{a^n}[/tex]

[tex](\frac{1}{2} )^{-4}=\frac{1}{\frac{1^4}{2^4} } =2^4=16[/tex]

If you trying to solve:

[tex]log(0.5)^{16}[/tex]

Then use reduction of power propierty:

[tex]log(x^y)=y log(x)[/tex]

Therefore:

[tex]log(0.5)^{16} =16 *log(0.5)=16*(-0.6931471806)=-11.09035489[/tex]
