Can't get the same answer as example

I am trying to follow an example, but I am unable to get the same results.
I was under the impression that when you have two numbers next to each other i.e. ai would mean A multiplied by I.

= ((65000/10000)1/4-1)*100
= (6.5 1/4 -1)*100
= (1.5967-1)*100
= 59.67%

but I get 1.6250 when I times 6.5 by 1/4 (6.5*0.25 = 1.6250) and I'm unable to get the 1.5967 when I do it.
Where am I going wrong?

Any help appreciated.

Math Focus: Yet to find out.
What is the original question exactly?

$\displaystyle \left( \left( \dfrac{65000}{10000} \cdot \dfrac{1}{4} \right) - 1 \right) * 100
$ ?

or $\displaystyle \left( \dfrac{65000}{10000} \cdot \left( \dfrac{1}{4} - 1 \right) \right) * 100
$ ?

or something else?

Don't forget your order of operations (BEDMAS/BODMAS). And pay attention to your brackets!

$\displaystyle =((f/s)1/y-1)*100$

spoken, it would be f (65000) divided by y (10000)
1/y is meant to be a fraction (1/4).

What I'm trying to use is the below method 2 part 4:

The $1/y$ should be an exponent: $6.5^{1/4} - 1 = 1.5967... - 1 = 0.5967$ to 4 decimal places.
