If the number $481*673$ is completely divisible by $9$,then the smallest whole number in place of $*$ will be

Find the square root of $(2.25)^{2} + 16 - 4(2.25) - \frac{(2.25)^{3}}{2.25 + 4} ?$

The difference between two positive integers is $3$. If the sum of their squares is $369$,then the sum of the numbers is

Two baskets together have $640$ oranges. If $\frac{1}{5}$ of the oranges in the first basket are taken to the second basket,the number of oranges in both baskets becomes equal. The number of oranges in the first basket is:

$\left[ {10 + \left\{ {4 \times \left( {\overline {\frac{2}{3} + \frac{1}{4}} \times \sqrt {\frac{{144}}{{121}}} + 23} \right) \div 12 + 5} \right\} - 3} \right] = ?$

For any integral value of $n$,$3^{2n} + 9n + 5$ when divided by $3$ leaves the remainder:
