Answer 1

Answer:

Step-by-step explanation:

Here is the answer. Hope it will help you.

Answer 2

Answer:

Formula used : (a+b)(a-b)=a²-b²

$→(y + \frac{1}{y} )(y - \frac{1}{y} )( {y}^{2} + \frac{1}{ {y}^{2} } ) \\ = ( {y}^{2} - \frac{1}{ {y}^{2} } )( {y}^{2} + \frac{1}{ {y}^{2} } ) \\ = \boxed{( {y}^{4} - \frac{1}{ {y}^{4} } )}$

• y⁴-1/y⁴ is the right answer.
