Chill, man, your life's not gonna end because you fail an assignment. And, if you fail it, think of it as something that had to happen somehow.

Think about it : what is 2% of $100000 ? Isn't that $\displaystyle \frac{100000}{100} \times 2$ ? So the first year we get $\displaystyle 100000 + \frac{100000}{100} \times 2$, right ? Now take this result as a number and apply the idea again. You should find a general formula that will give you the value of timber given the years from now

And then question b) is basically pluggin' in the number.

**PS** : please avoid the F word ... there are all-age people on this forum and we don't necessarily need to see this.

**PS2** : by the way Awsom Guy, your answer is wrong. This doesn't take into account the increasing value of T and thus the increasing value of 2% of T.
