Remark
That is going to result in some very heavy duty money.
Equation
P_n = 6^n
P_n = payment in nickels
Check
Let n = 1
P_n = 6^1
P_n = 6
P_3 = 6^3
P_3 = 216 Just what the question said we should get
Question
Find P_8
Put the formula into your calculator like this.
6
^ Some calculators x^y and others use y^x instead of ^
8
=
Do they want scientific notation for the first 2 blanks? Have you studied that yet?
P_8 = 1.6796 * 10^6
First blank = 1.6796
The second one = 6
The third one is 1,679,616
