Step-by-step explanation:

$a - \frac{1}{a} \\ \frac{ {a}^{2} - 1 }{a} \\ = \frac{ {(2 + \sqrt{3} )}^{2} - 1}{2 + \sqrt{3} } \\ = \frac{7 + 4 \sqrt{3} - 1 }{2 + \sqrt{3} } = \frac{6 + 4 \sqrt{3} }{2 + \sqrt{3} } = 2 \sqrt{3}$

$\sf{3. \ \ Given : \dfrac{2}{3} - \dfrac{5}{4} + \dfrac{7}{2}}$

Let us solve the first two fractions : The LCM of 3 and 4 is 12

$\sf{\implies \dfrac{4(2) - 5(3)}{12} + \dfrac{7}{2}}$

$\sf{\implies \dfrac{8 - 15}{12} + \dfrac{7}{2}}$

$\sf{\implies \dfrac{-7}{12} + \dfrac{7}{2}}$

LCM of 2 and 12 is 12

$\sf{\implies \dfrac{-7 + 7(6) }{12}}$

$\sf{\implies \dfrac{-7 + 42}{12}}$

$\sf{\implies \dfrac{35}{12}}$

$\sf{\implies 2 +\dfrac{11}{12}}$

$\sf{\implies 2 \dfrac{11}{12}}$

---------------------------------------------------------------------------------------

$\sf{4. \ \ Given : \dfrac{(2 - 7)^2 + 5}{3}}$

$\sf{\implies \dfrac{(-5)^2 + 5}{3}}$

$\sf{\implies \dfrac{25 + 5}{3}}$

$\sf{\implies \dfrac{30}{3}}$

$\sf{\implies 10}$
