If \(x = \sqrt {\left( {1.96} \right)} - \sqrt {\left( {0.04} \right)}\) then the value of x is
Solution
Correct Answer: Option A
The given expression may be simplified as:
\(\Rightarrow x = \sqrt {\left( {1.96} \right)} - \sqrt {\left( {0.04} \right)}\)
\(\Rightarrow x = \sqrt {\frac{{196}}{{100}}} - \sqrt {\frac{4}{{100}}}\)
\(\Rightarrow x = \frac{{\left( {\sqrt {196} - \sqrt 4 } \right)}}{{\sqrt {100} }}\)
\(= \frac{{14 - 2}}{{10}}\)
= 1.20
