Question

If X-1/X=6 then X4-1/X4=?

Answer 1

Step-by-step explanation:

$x - 1 \x = 6$

$6x = x - 1$

$6x - x = - 1$

$5x = - 1$

$x = - 1 \5$

then put the value of x in second equation

Answer 2

Answer:

9/4

Step-by-step explanation:

First we will find the valve of X

X-1/X =6

X-1=6X

-1 = 5X

X = -1/5

Then we will put the valve of X in X4-1/X4

=(-1/5×4 - 1)/(-4/5)

=(-9/5)/(-4/5)

- & - sign will b cancel out

=9/5×5/4

=9/4 Ans
