• A. $52$
• B. $0.52$
• C. $0.052$
• D. $5.2$

Answer 1

The correct option is C $0.052$

$\sqrt{0.0676}=\sqrt{\frac{676}{10000}}=\sqrt{\frac{26\times 26}{100\times 100}}=\frac{26}{100}=0.26$
$\sqrt{0.04}=\sqrt{0.2\times 0.2}=0.2$
$\sqrt{0.0676\times 0.04}=\sqrt{0.0676}\times \sqrt{0.04}=0.26\times 0.2=0.052$
