$${\frac{{\mathtt{5}}}{{\mathtt{100}}}} = {\mathtt{0.05}}$$

The ratio between the circumference of a circle and its diameter.

That's the hard way to do it.

The easy way: call d the length of the diagonal, and s the length of the side.

The ratio $${\frac{{\mathtt{d}}}{{\mathtt{c}}}}$$ is equal to φ for any regular Pentagon.

Yes, but there's another way to find the length of the diagonal. An easier way...

Your answer is in the wording of question 1... But that's because I used the word "size" instead of "lenght".

Is that $${{\mathtt{25}}}^{\left({\frac{{\mathtt{3}}}{{\mathtt{2}}}}\right)} = {\mathtt{125}}$$

or $${\frac{{{\mathtt{26}}}^{{\mathtt{3}}}}{{\mathtt{2}}}} = {\mathtt{8\,788}}$$ ?

Is that log(x)-1 or log(x-1) ?

$${\frac{\left({\frac{{\mathtt{3}}}{{\mathtt{4}}}}\right)}{\left({\frac{{\mathtt{2}}}{{\mathtt{7}}}}\right)}} = {\frac{{\mathtt{21}}}{{\mathtt{8}}}} = {\mathtt{2.625}}$$

The 3rd term would be $$2*3^2 -4=2*9-4=18-4=14$$
