Question

if n-1/n=1/4,then n+1/n is equal to...
pls answer guyzz​

Answer 1

Answer:

7/4

Step-by-step explanation:

n-1/n=1/4

do cross multiplication

=4n-4=n

by transposing-4to right side& n to left side

=4n-n=4

=4n-n=3n

=3n=4

=n=4/3

and now place the value of n in n+1/n

here n=4/3

4/3+1/4/3

do L.C.M for4/3+1=4+3/3

the L.C.M of4/3+1=7/3

in the first eqation=4/3+1/4/3

=7/3/4/3

here 3&3 get cancelled

so the answer=7/4

Answer 2

Answer:

n-1/n = 1/4

(n-1/n)^2 = (1/4)^2

(n+1/n)^2 -4 = 1/16(because we can also write (n-1/n)^2 = (n+1/n)^2 -4n×1/n)

(n+1/n)^2 = 1/16 +4

n+1/n = √65/16

= √65/4

Required Answer :

= √65/4
