Question

Solving Equations In Exercise,solve the equation for
e - 1/x = e1/2

Answer 1

x=-2

Explanation:

We are given that

`e^{-(1)/(x)}=e^{(1)/(2)}`

We have to solve the given equation

Taking natural log ln on both sides then we get

`ln(e^{-(1)/(x)})=ln(e^{(1)/(2)})`

`-(1)/(x)=(1)/(2)`

By using the property

`lne=1`

`-2=x`

`x=-2`

Hence, the solution of equation x=-2
