Question 1

If

, then find the value of :
(I)

$√(a) \: - (1)/( √(a) )$
(ii)

${a}^(2) + \frac{1}{ {a}^(2) }$
plz post the correct answer

Question 2

Answer:

1) -2√2 2) 98

Explanation:

the picture 1 and 2 are for question 1

the picture 3 and 4 are for question 2

$If a = 5 - 2 √(6) , then find the value of : (I) √(a) \: - (1)/( √(a) ) (ii) {a}^(2) + \frac-example-1$

$If a = 5 - 2 √(6) , then find the value of : (I) √(a) \: - (1)/( √(a) ) (ii) {a}^(2) + \frac-example-2$

$If a = 5 - 2 √(6) , then find the value of : (I) √(a) \: - (1)/( √(a) ) (ii) {a}^(2) + \frac-example-3$

$If a = 5 - 2 √(6) , then find the value of : (I) √(a) \: - (1)/( √(a) ) (ii) {a}^(2) + \frac-example-4$
