If we write:
(a+b)²
it means:
(a+b)(a+b)
however, if I want to mean the square of the sum, how would I write it algebraically?
Math notation for binomial square
I don't understand the question.
a + b = sumab
sumab2 = (a + b)2 = (a + b)(a + b)

Or with numbers to show an example:
3 + 4 = 7
72 = (3 + 4)2 = (3 + 4)(3 + 4)
49 = 9 + 12 + 12 + 16
49 = 49
Yes, it is equivalent, what an idiot of me...
(a+b)2 is square of the sums, perhaps you were confusing it with the sum of the squares, (a2 + b2), ala pythagoras'?
