3. It is three. Log2.8 means log2.2^3 thus = 3

Answer:

[tex]log_{2} 8[/tex] = 3

Step-by-step explanation:

We have to evaluate cc

Let [tex]log_{2} 8[/tex] = y

then [tex]2^{y}=8[/tex]

[Since we know by the definition of logarithm [tex]log_{a} b=c[/tex] then [tex]a^{c}=b[/tex]]

Now [tex]2^{y}=2^{3}[/tex]

So y = 3

Therefore, [tex]log_{2} 8[/tex] = 3 is the answer.
