I believe it is the commutative property of multiplication. Commutative property is you can put the numbers in any order and it will have the same end result. I got multiplication because it is multiplication.
Hope this helps!
Let's assume there are 52 weeks in a year,
so we have , rate= 6.4/52= 0.123%
now ,
c.i = 5000[(1+0.123/100)^3×52 -1]
= $1056.911
took me a while
It’s 4d-5=2d+7 try my best
Please upload the figure too
