Each of x, y and z is a rational number such that: x + y * ³√2 + z * ³√4 = 0.

Prove that x=y=z=0 is the only possible solution to the above equation.

Delta:  Δ
Pi:       π
root:    √
Sigma: Σ

Here I used the button mentioned in my first comment here, the one right beside the "Drop-down" labeled "Formatting".

In fact, back at that location I tried two different additions of "ΔπΣ√" using Normal and Pre-Formatted from the dropdown.

Why do you not get such results Charlie?
