Detailed Solution

Given that,

34 − 13

By obtaining the L.C.M. of the denominators and converting the fractions into like fractions, fractions with different denominators can be subtracted.
Now, LCM of 3 and 4 will be,

2 3, 4 2 3, 2 3 3, 1 1,1

So, L.C.M of 4 and 3 is

2 × 2 × 3 = 12

On solving further, we get,

\Rightarrow \frac{3 \times 3 - 1 \times 4}{12}

\Rightarrow \frac{9 - 4}{12}

\Rightarrow \frac{5}{12}

Hence,

34 − 13 = 512

.
Therefore, correct answer is option (1).
