1. \:  \sqrt[3]{1.728}  =  \sqrt[3]{1.2 \:  \:  \:  \: 1.2 \:  \:  \:  \: 1.2}  \\   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  = 1.2 \\  \\
1. 1.2
2. \:  \sqrt{3.61}  =  \sqrt{1.9 \:  \:  \:  \: 1.9}  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:    = 1.9
2. 1.9
3. \:  \sqrt[3]{512}  \times 729 \div 1000
Firstly, We find Cube root.
So,
 \sqrt[3]{512}  =  \sqrt[3]{8 \:  \:  \: 8 \:  \:  \: 8 }  \\  \: \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  = 8 \\
Then,
8 \times  \frac{729}{1000}  \\ 2 \times  \frac{729}{250}  \\ 5.832
3. 5.832
