Answer:
4 option D
Step-by-step explanation:
Note that log2(2^n)=n
Thus we have:
Log2(2)+log2(8)=1+log2(2³)=1+3=4
Let the original fraction be

Now let's increase both numerator and denominator by 2:

This produces a 1/12 increase:

The left hand side can be rearranged as

Invert both sides:

Solve the quadratic equation:

So, in the first case, the original fraction is

In the second case, we have
