For this case we must find the value of the following expression:

We have to:

Substituting:

By definition of properties of powers and roots we have:
![\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}](https://tex.z-dn.net/?f=%5Csqrt%20%5Bn%5D%20%7Ba%20%5E%20m%7D%20%3D%20a%20%5E%20%7B%5Cfrac%20%7Bm%7D%20%7Bn%7D%7D)
So:

So we have to:

Answer:
Cynthia will have to pay $152.16 extra in finance charges.
Step-by-step explanation:
Cynthia had a credit card with a 17% APR and a $3,265 balance.
Cynthia’s credit card company has increased her interest rate to 21%.
Here we have two scenarios, 1st when p = 3265 r = 17% and n = 24
Second when p = p = 3265 r = 21% and n = 24
Scenario 1:

EMI formula is :

Putting the values in formula we get;

= 
EMI = $161.43
Scenario 2:
r = 
Putting the values in formula we get;

= 
EMI = $167.77
Now, difference in EMI's =
dollars
And for 24 months this amount becomes =
dollars
Therefore, Cynthia will have to pay $152.16 extra in finance charges.
