A) 1
B) 10
C) 100
D) 0.1
Correct Answer: B
Solution :
\[\sqrt{\frac{{{(0.1)}^{2}}+{{(0.01)}^{2}}+{{(0.009)}^{2}}}{{{(0.01)}^{2}}+{{(0.001)}^{2}}+{{(0.0009)}^{2}}}}\] \[=\sqrt{\frac{0.01+0.0001+0.000081}{0.0001+0.000001+0.00000081}}\] \[=\sqrt{\frac{0.010181}{0.00010181}}=\sqrt{\frac{10181\times 100}{10181}}=\sqrt{100}=10\]You need to login to perform this action.
