# Interactive maxima question on fraction value during solve()

# Context

I executed this code

```
var('x, k')
As(x) = (2*k/(k-1))^(-0.5) * (( x^(2/k) - x^((k+1)/k)) )^(-0.5)
dAs(x) = As.derivative(x)
ns = solve(dAs(x), x)
print ns
```

which results in

[ (1/(x^((k - 2)/k))) == 1/2*(k + 1)*x^(1/k) ]

My goal is the have sage solve this equation for x, where the result should look something like

```
x == ( 2/(k+1) )^( k/(k-1) )
```

# The Problem

This code

```
myEqs = [ (1/(x^((k - 2)/k))) == 1/2*(k + 1)*x^(1/k) ]
assume(k>1)
solve(myEqs, x)
```

results in

Traceback (click to the left of this block for traceback) ... TypeError: Computation failed since Maxima requested additional constraints (try the command 'assume(k-1)/k>0)' before integral or limit evaluation, for example): Is (k-1)/k an integer?

But the suggested `assume(k-1)/k>0)`

isn't even valid syntax.

**My question**: How can I cover this question with `assume()`

so that maxima doesn't have to ask (and hence fail because it doesn't support interactive communication with another process)?
