Question

a3+b3 varify by an activity

Answer 1

a^3 +b^3 =(a+b)(a^2 -ab +b^2) =a^3 -a^2b +ab^2 +a^2b -ab^2 +b^3 =a^3 +b^3

you have thought it hence ?

good luck

bye

Answer 2

this is not true ans. of my question

Answer 3

Can you explain the question?

I don't even understand what we're trying to 'verify' here. The formula, a^3 + b^3 = (a + b)(a^2 - ab + b^2)? Are we supposed to make some 'activity' that proves that the formula is true?
