1.	34^2=_____(a) 1156(b) 1256(c) 1356(d) 1456This question was posed to me in quiz.My question comes from Finding the Square of a Number topic in portion Squares and Square Roots of Mathematics – Class 8
Answer» CORRECT answer is (a) 1156 Easiest explanation: In ORDER to calculate the square of 34 we use the formula, (a+b)^2, where we CONSIDER a=30 and b=4 Therefore (30+4)^2 = 30^2+2×30×4+4^2 Therefore (30+4)^2 = 900+240+16 Therefore (30+4)^2 = 1156.
