Answer : B
Explanation
Given expression is a2 + 2ab + b2 where a = 2.43, b = 7.57 = (a+b)2 = (2.43 + 7.57)2 = 102 = 100
Answer : C
Explanation
0.13 / x2 = 13 => 13x2 = 0.13 => x2 = 0.13/13 = 13/100 x 1/13 = 1/100 => x = 1/10 = .1
Answer : A
Explanation
Given expression is a3 + b3 + 3ab - 1 where a - .98 and b =.02 ∴ .983 + .023 - 3 x .98 x .02 - 1 = (a+b)3 -1 = (.98 + 0.02) - 1 = 0
