Question

2 { 1 / a + 2 } = 5 - 2 / a​

Answer 1

Answer:27

Step-by-step explanation:It is given that,

a  2 −1/a  2 =5

So,

By using the formula, (a+b)  

2 [a  2  −1/a 2  ]  2  =a  

4 +1/a  4 −2 [a  2  −1/a  2  ]  2  +2=a  

4 +1/a  4

 Substitute the value of a  

2 −1/a  2  =5, we get

5  2  +2=a  

4 +1/a  4

 a  4 +1/a  4  =25+2

=27
