Question

The value of $\sqrt{\frac{0.00001225}{0.00005329}}-3\sqrt{\sqrt{0.000064}}$ =

• A. $0.2$
• B. $0.279$
• C. $0.249$
• D. $0$

Answer 1

The correct option is B $0.279$

$\sqrt{\frac{0.00001225}{0.00005329}}-\sqrt[3]{3\sqrt{0.000064}}$

$=\frac{0.0035}{0.0073}-\sqrt[3]{30.008}$

$=\frac{0.0035}{0.0073}-0.2$

$=\frac{0.0035-0.00146}{0.0073}$

$=\frac{0.00204}{0.0073}$

$\approx 0.279$

$\therefore$ The answer is $0.279$. $\left[B\right]$
