Question

Evaluate log2 8. Need help with this it is urgent!!

Answer 1

Answer:

$log_{2} 8$ = 3

Step-by-step explanation:

We have to evaluate cc

Let $log_{2} 8$ = y

then $2^{y}=8$

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

Now $2^{y}=2^{3}$

So y = 3

Therefore, $log_{2} 8$ = 3 is the answer.

Answer 2

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