Answer 2

The given expression is {3^(-1)-4^-1}-1

We have to find the value of given expression.

The power of given expression is -1, so we can written as

$\frac{1}{\frac{1}{3}-\frac{1}{4} } -1$,  first of solve $\frac{1}{3}$ minus $\frac{1}{4}$ we get,$\frac{4-3}{12} =\frac{1}{12}$,

$12$ is goes to numerator it becomes $12-1=11$

Therefore, 11 is required answer.
