How do I get the answer 4?

First I would have calculated the phase resistance (RL circuit Z²=R²+XL²) and then I phase and then I total and then the power P= root 3 * 400V * I total.

But that doesn't give me the right result.

When you're counting Z, you're expecting the appearance, but you're in demand for the performance… You have to calculate the CosPhi…
