Question

if x-1/x = 5 then find the value of (x^3+1/x^3)

plss say as fast as possible i want with complete explanation and answer

Answer 1

Step-by-step explanation:

x-1/x = 5

x-1 = 5x

x-5x = 1

-4x = 1

x= -1/4

putting value of x in(x^3 + 1/x^3)

=(-1/4)^3 + 1/(-1/4)^3

= -1/64 + 1/(-1/64)

= -1/64 - 64
