Answer 2

Given:

• $\sf{5}^{ - 1} - {6}^{ - 1}$

To find:

• The value of the given expression.

Solution:

We know that:

$\sf a^{-1}=\dfrac{1}{a}$

Using this formula, we can rewrite the given expression as:

$\sf{5}^{ - 1} - {6}^{ - 1}=\dfrac{1}{5}-\dfrac{1}{6}$

Now, we need to find the common denominator of these fractions. The smallest common multiple of 5 and 6 is 30.

$\sf{5}^{ - 1} - {6}^{ - 1}=\dfrac{1}{5}-\dfrac{1}{6}=\dfrac{6}{30}-\dfrac{5}{30}=\dfrac{1}{30}$

Therefore, the value of the given expression is $\sf \dfrac{1}{30}$.
