Sales tax on the item is ~

Cost of the item is ~
![{ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \$390](https://tex.z-dn.net/?f=%7B%20%5Cqquad%7B%20%5Csf%7B%20%5Cdashrightarrow%7D%7D%7D%20%20%5C%3A%20%20%5C%3A%20%5Csf%20%5C%24390)
sale tax rate is ~
![{ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: \dfrac{ \$23.40}{ \$390} \times 100](https://tex.z-dn.net/?f=%7B%20%5Cqquad%7B%20%5Csf%7B%20%5Cdashrightarrow%7D%7D%7D%20%20%5C%3A%20%20%5C%3A%20%5Csf%20%5C%3A%20%5Cdfrac%7B%20%5C%2423.40%7D%7B%20%5C%24390%7D%20%20%5Ctimes%20100)

Therefore, the sales tax rate is 6 %
I^32 = (i^4)^8 and i^4 = 1
so (i^4)^8 =1^8 = 1
The trick on all questions like this is to get as many i^4’s out of the way, since they’re all just 1s.
