Apply operation to each element of an array

I have an array of numbers x1, x2, x3.... I want to obtain an array of numbers y1, y2, y3... such that yi = ceil((3/xi)^2). Is there a way to do this in one line of code without a for loop? I could do it with a for loop but I feel like I should be able to just apply the operation elementwise in a one line command.

Something like

Y = ciel((3/X)^2))

but of course that is not allowed

You should use element-wise operations

In your case

Y = ceil((3./X).^2))

Thank you. I wondered about using the dot for element wise, but didn’t realise I could use it twice in the same operation like that
