Answer 3

Let's break down the expression step by step:

1. $(13)^{-1}$ means the reciprocal of 13, which is $\frac{1}{13}$.
2. $(-67)^{0}$ means any non-zero number raised to the power of 0 is 1. So, this term is 1.
3. $(12)^{2}$ means 12 raised to the power of 2, which is 144.
4. $2:2$ means dividing 2 by 2, which is 1.

Now we can substitute these values into the expression:

$\frac{1}{13} - 1 + 144 \div 1$

Simplify the division:

$\frac{1}{13} - 1 + 144$

Now subtract and add the values:

$\frac{1}{13} - \frac{13}{13} + 144$

$\frac{1 - 13}{13} + 144$

$\frac{-12}{13} + 144$

Now we add the fractions and the number:

$\frac{-12 + 1872}{13}$

$\frac{1860}{13}$

This fraction cannot be simplified further, so the result is approximately:

$\frac{1860}{13} \approx 143.08$
