The least prime number is

$4433.764 - 2211.993 - 1133.667 + 3377.442 = ?$

$5999.99 + 1999 \div 39.99 \times 50.01 = ?$

Arranging the following in descending order,we get $\sqrt[3]{4}, \sqrt{2}, \sqrt[6]{3}, \sqrt[4]{5}$.

The product of two numbers is $120$. The sum of their squares is $289$. The sum of the two numbers is

If a number is multiplied by $\frac{3}{5}$ of itself,the value so obtained is $3^{2}$ less than $12^{2}$. What is $\frac{5}{3}$ of that number?
