Question

if z - 1/ z = 6 find value of z4 +1/ z4​

Answer 1

Answer:

9/20

Step-by-step explanation:

z-1/z=6

z-1=6z

-1=6z-z

-1=5z

z=-1/5

z4+1/z4

(-1/5)4+1/(-1/5)4

(-4/5)+(-5/4)

by doing lcm

(-16/20)-(25/20)

therefore

-41/20

Answer 2

Answer:

1296

Step-by-step explanation:

If z - 1/ z = 6

So,= z^4 +1/ z^4

=(z+1/z)^4

value of z - 1/ z = 6

=6^4

=1296
