Answer 2

Step-by-step explanation:

$a + \frac{1}{a} = 3 \\ {(a + \frac{1}{a})}^{3} = 27 \\ {a}^{3} + \frac{1}{ {a}^{3} } + 3(a + \frac{1}{a}) = 27 \\ {a}^{3} + \frac{1}{ {a}^{3} } + 3 \times 3 = 27 \\ {a}^{3} + \frac{1}{ {a}^{3} } = 18 \\ ( {a}^{3} + \frac{1}{ {a}^{3} } )^{2} = 324 \\ {a}^{6} + \frac{1}{ {a}^{6} } + 3({a}^{3} + \frac{1}{ {a}^{3} } ) = 324 \\ {a}^{6} + \frac{1}{ {a}^{6} } + 3(18)= 324 \\ {a}^{6} + \frac{1}{ {a}^{6} } = 324 - 54 = 270$
