Determine whether the given number is divisible by $8$ or not 

$5362504$

Celestial objects (like comets, planets and stars) have been observed by civilizations throughout history. Some people viewed these (especially comets and eclipses) as omens of future events while others interpreted them as signs from their gods. Halley's comet orbits the Earth every $76$ years while comet Swift-Tuttle has a $132$-year orbit. If they were to pass by Earth in the same year, about how many years later would they again pass by Earth in the same year?

Use the numbers $3, 4, 6 \text{and} 12$ along with one multiplication and two divisions to write down another expression that equals $24$.

Using any numbers of your own choosing, write down an expression that uses four different operations (choosing from multiplication, division, subtraction, addition, exponent, and root) where the answer is $20$. Remember to obey the correct order of operations.

Using any numbers of your own choosing, write down an expression that includes at least three exponents, one set of parentheses, one multiplication, and one addition, where the answer is $8$.

In a traditional Mayan medicine garden, herbs were planted for their healing powers, such as Bougainvillea for its antibiotic properties and Calendula for its anti-viral and anti-inflammatory properties.

If a field was $54$ land rods (an ancient unit of measurement) by $30$ land rods, what are the dimensions of the largest square plots of a single herb that could be planted?
