What is the value of \(\sqrt{0.0169}+\sqrt{1.44}\)?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 1.33
The square root of a decimal has half as many decimal places as the number under the root (when that number has an even count of decimal places).
\(\sqrt{169}=13\), and 0.0169 has 4 decimal places, so \(\sqrt{0.0169}=0.13\)
\(\sqrt{144}=12\), and 1.44 has 2 decimal places, so \(\sqrt{1.44}=1.2\)
\(0.13+1.2=1.33\)
