What is the correct answer

We have : (11+5)2
 
The correct answer?
a) 112+52
b) 28
c) -162

Andrew M.

(11+5)2
Arthur worked this out, and all the comments are
appropriate.  Still, it isn't hard to eliminate two of
these answers straight off.
There are no negatives involved in the expression
so c is out.
Note (a+b)2 = a2 + 2ab + b2 , not a2 + b2
which eliminates answer a.
 
That only leaves c... 28
 
A quck plug into a calculator will show
that 28 = 256 and 162 = 256

I would recommend solving the expression in the question and solve each expression in the answers and see which answer matches.  Do you know how to solve these expressions?
