Question

pls tell me what is the answer​

Answer 1

Answer:

$({a + \frac{1}{a} })^{2} = {a}^{2} + ({ \frac{1}{a} })^{2} + 2 \times a \times \frac{1}{a}$

$= > ({a + \frac{1}{a} })^{2} = {a}^{2} + \frac{1}{ {a}^{2} } + 2$

$= > ( {a + \frac{1}{a} })^{2} = 47 + 2$

$= > ({a + \frac{1}{a} })^{2} = 49$

$= > a + \frac{1}{a} = \sqrt{49}$

$= > a + \frac{1}{a} = 7$
