Revisiting the Value of (2+5)2: 9 or 49?

[Gringo123]

Is the value of this expression 49? The andwers in my book say that it should be 9!
(2 + 5)²

Unless your book has a different meaning for it, 7x7 will be 49.

5 + 2², on the other hand...

Thanks guys. It's laid out exactly as I have written it so I doubt it's meant to be 5 + 2^2.
Thanks again

If the plus sign were a minus sign, you'd get (-3)²=9. Could be a typo or a sign mistake somewhere along the way.

Or the book forgot to add the 4...

I cannot imagine an answer that is much more INcorrect for this than 9!.

Thanks a lot everyone. I wouldn't be the 1st time that a typo had appeared in this book that I'm using. I think that is what has happened. I just wanted to make sure I wasn't missing somthing as I am teaching myself maths via books and internet.
