Question

If
$y + \frac{1}{y} = 3$
Then Find the value of
$y {5} + \frac{1}{y {5} }$
​

Answer 1

Answer:

7/5

Step-by-step explanation:

y+1/y =3

5y+1/5y

y+1=3y

1/2 = y ----- eqn.1

substituting in another eqn.

5/2 + 1/5/2

therefore taking LCM

5+2/2/5/2

7/2/5/2

therefore 2 gets cancelled

7/5 is the answer
