Question

Solve:

${1.5}^2\times \sqrt{0.0225}=?.$

• A. 0.0375
• B. 0.3375
• C. 3.375
• D. 0.003375

Answer 1

The correct option is B 0.3375

${1.5}^2\times \sqrt{0.0225}$

$\Rightarrow 2.25\times \sqrt{\frac{225}{10000}}$

$\Rightarrow 2.25\times \frac{15}{100}$

$\Rightarrow \frac{225}{100}\times \frac{15}{100}$

$\frac{3375}{1000}\Rightarrow 0.3375$
