The answer:
the full question is as follow 
What is the value of <span>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, </span>log0.5 ^16 = 16log0.5, and log0.5 = -0.69, 
<span>finally
</span>log0.5 ^16 = 16log0.5=16*(-0.69)= -11<span>

Answer:

You mean ?

log_0_._5 (16) =-4

or

You mean?

log(0.5)^{16}=-11.09035489

Step-by-step explanation:

If you trying to solve:

log_0_._5(16)

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

log_xy=z\Rightarrow x^z=y

0.5^z=16  

Rewrite 0.5 as:

0.5=\frac{1}{2}

As you may know:

2^4=16

then\\\\z=-4

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

a^{-n}=\frac{1}{a^n}

(\frac{1}{2} )^{-4}=\frac{1}{\frac{1^4}{2^4} } =2^4=16

If you trying to solve:

log(0.5)^{16}

Then use reduction of power propierty:

log(x^y)=y log(x)

Therefore:

log(0.5)^{16} =16 *log(0.5)=16*(-0.6931471806)=-11.09035489

Solve the equation: -2/5 n = -30<br> A. n=-75<br> B. n=-12<br> C. n=12<br> D. n=75
OLEGan [10]
Assuming your equation is: -2/5n = -30

-2/5n = -30    <- We get rid of the "/5n" by multiplying each side by 5n
-2 = -30 * 5n
-2 = -150n
-1 = -75n
75n = 1

But this doesn't match up with any of your answers, so if you wouldn't mind giving me the equation again, i'll work it out
