Question

3√0.729÷√0.0009×(0.25)^1upon2-3√3.375​

Answer 1

Step-by-step explanation:

$3 \sqrt{0.729} \div \sqrt{0.0009} \times {(0.25)}^{ \frac{1}{2} } - 3 \sqrt{3.375}$

$= 3 \sqrt{ \frac{0.729}{0.0009} } \times 0.5 - 3 \sqrt{3.375}$

$= 1.5 \sqrt{ \frac{7290}{9} } - 3 \sqrt{3.375}$

$= 1.5 \sqrt{810} - 3 \sqrt{3.375}$

$= 1.5 \times 9 \sqrt{10} - \sqrt{1.5 \times 225}$

$= 13.5 \sqrt{10} - 15 \sqrt{1.5}$

$= 15 \sqrt{5} (0.9 \sqrt{2} - \sqrt{0.3} )$
