What is the Boolean Equation for This Karnaugh Map?

[olimain]

Hi, this should be simple but it's really giving me difficulty. Does anybody know what the Boolean Equation would be for this Karnaugh Map?

Thanks in advance,

Oliver

Maybe if you could show some working or where you find the difficulty we could help .

How many groups of minterms do you see?

Urgh, this is kinda bad but:

Qd(QcQa' + QaX' + QbQc' + XQb') + Qa'Qb'Qc'Qd'X'

I know it's not pretty, but it's something.
