Question

if x is equals to 1 by 5 minus x find x cube plus one by x cube​

Answer 1

If x=1/5-x

=x+x=1/5

=2x=1/5

=x=1/5×1/2

=x=1/10.........................i

Then

X^3+1/x^3

=(1/10)^3+[1/(1/10)^3]

=1/1000+1000

LCM is 1000

So

1/1000+1000

=(1+1000000)/1000

=1000001/1000

=1000.001

HOPE THIS HELPS.....
