Which of the following is closest to zero ?

A. $${\left( {0.09} \right)^2}$$

B. $$0.09$$

C. $${\left( {1 - 0.9} \right)^2}$$

D. $$1 - {\left( {0.9} \right)^2}$$

Answer: Option A

Solution(By Examveda Team)

(a) (0.09)² = 0.0081
(b) 0.09
(c) (1 - 0.9)² = (0.1)² = 0.01
(d) 1 - (0.9)² = 1 - 0.81 = 0.19
Clearly, 0.0081 < 0.01 < 0.09 < 0.19
So, 0.0081 is closest to zero.
