解释：
这个公式能用汉语写一下么，能简明分析下么
NO.PZ2018062003000200 问题如下 When the reexchange rate( assuming mestic currenis pricurrenan foreign currenis base currency) increase whiof the followings is most likely to associatewith crease? A.Nominexchange rate. B.mestic prilevel. C.Foreign prilevel. B is correct.The formula of reexchange rate is :Reexchange rate (f) =Sf×(Pf/P{}_{(f)\text{ }}=S_f\times(P_f/P_(f) =S/f×(Pf/P) crease in the mestic prilevel increases the reexchange rate because it implies crease in the purchasing power of the mestic currencompareto foreign currency.考点 exchange rate解析 Reexchange rate (f) =Sf×(Pf/P{}_{(f)\text{ }}=S_f\times(P_f/P_(f) =S/f×(Pf/P)根据上述公式，较高的Nominexchange rate，较高的Foreign prilevel，以及较低的mestic prilevel会产生较高的Reexchange rate 这道题应该是用这张图的公式。我是不是可以认为，mestic prilevel就是CPI(？

NO.PZ2018062003000200 mestic prilevel. Foreign prilevel. B is correct. The formula of reexchange rate is : Reexchange rate (f) =Sf×(Pf/P{}_{(f)\text{ }}=S_f\times(P_f/P_(f) =S/f×(Pf/P) crease in the mestic prilevel increases the reexchange rate because it implies crease in the purchasing power of the mestic currencompareto foreign currency. 考点 exchange rate 解析 Reexchange rate (f) =Sf×(Pf/P{}_{(f)\text{ }}=S_f\times(P_f/P_(f) =S/f×(Pf/P) 根据上述公式，较高的Nominexchange rate，较高的Foreign prilevel，以及较低的mestic prilevel会产生较高的Reexchange rate实际利率上升，名义利率不变，通货膨胀率下降，本币升值，所以base currency上升，另外那个就下降，这样理解对吗
NO.PZ2018062003000200 pricurren和 base currency分别是比例里的哪个啊 举个例子
NO.PZ2018062003000200 所以reexchange rate是默认 price/base吗 还是看具体题目要求？
