Use the `sqrt()`

and `log()`

functions from the `math`

module, along with the
built-in `round()`

function to print the answers to the following questions to
the screen.

- How long is one side of a square plant census quadrat that has an area of 10 m^2, rounded to two decimal places?
- The number of species in a region can be estimated based on the area
of that region using the equation
`number of species = 3.5 + 0.25 * log(area)`

. The logarithms in this equation are natural logarithms. For an area of 8 km^2 what is the estimated number of species rounded to the nearest integer.
