Shallow buttress roots so the plants can reach the nutrients at the top of the soil.
The climate means vegetation decomposes quickly when it dies.
The vegetation releases nutrients back into the top of the soil.
Can any of you give me a synonym of 'rash'? Used as an adjective, the sentence is:
'Anyone rash enough to write a book with a title like this had better brace themselves for a postbag crammed with letters in erratic handwriting enclosing complex symbolic diagrams.'
Thank you in advance, might pop up requesting some help again, have a huge translation assignment due to Monday.

Reckless, crazy.

to the powerCan't understand your notation, sorry.
Do you mean y^12t? What are the numbers in brackets for?
12t to the power of 8
12t^8/3t^6*6t^2
Combine the indicies on the denominator into one term --> 18t^8.
12t^8/18t^8.
Remember that 1/y^a = y^-a. And (y^a)*(y^b) = y^(a+b)
Therefore dividing means you subtract the power. The powers are the same on the numerator and denominator, so the t term cancels and you are left with 12/18, which is equal 2/3.
Do the same for the 2nd question, combine both numerator and denominator into single terms.
16s^6*2s^5/4s^7*3s^8 = 32s^11/12s^15.
Now remember you minus the bottom power from the top power.
--> (32/12)s^(11-15)
=(8/3)s^-4
Which is equivalent to: 8/(3s^4)
Ask if anything confused you.

Thanks Joel, the only problem is the answer to the first question in my text book is 2/3^5. But if that doesn't mean anything to you atleast I can show my teacher I tried

Actually I don't know how you got 8/3 by taking away 32/12

You either wrote the question down wrong or your textbook is wrong.
They're equivalent fractions. I just reduced it to the simplest form.
