Find the nonpermissible replacement for n in the following expression : -8/5n

We are given expression

we know that

this is rational expression

And any rational expression is undefined when it's denominator =0

so, for finding non-permissible values of n , we set denominator =0

and then we can solve for n

denominator is 5n

Divide both sides by 5

so, we get

So, the non-permissible replacement for n in this expression is 0.........Answer

2/3x=1-2

X=-1*3/2

X=-3/2

So is - 3/2
