1.	What can be general formula to find square of any number?(a) (a&pm;b)^2(b) a^2(c) a(d) bI got this question during an interview.My question comes from Finding the Square of a Number in chapter Squares and Square Roots of Mathematics – Class 8
Answer» Right choice is (a) (a&pm;B)^2 Easiest EXPLANATION: The general formula of FINDING square of any number is (a&pm;b)^2. Option a^2 cannot be correct because if we need to find square of number such as 23 the METHOD USING the general formula (a&pm;b)^2 would be more easier. Hence the correct option is (a&pm;b)^2.
