If M = 0.1 + (0.1)2 + (0.01)2 and N = 0.3 + (0.03)2 + (0.003)2, then what is the value of M + N?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 (i.e. 0.411009)
M = 0.1 + (0.1)2 + (0.01)2 = 0.1101
N = 0.3 + (0.03)2 + (0.003)2 = 0.3 + 0.009 + 0.000009
= 0.300909
M + N = 0.1101 + 0.300909
M + N = 0.41009
