Remember
(ab)^c=(a^c)(b^c) and
x^{-m}= \frac{1}{x^m}
so
(-2)^{-3}= \frac{1}{(-2)^3}= \frac{1}{(-1)^3(2)^3}=\frac{1}{(-1)(8)}=\frac{1}{-8}=\frac{-1}{8}

Using the following production tally, determine how many total mousetraps were produced during a shift: Quantity per package: 60
timofeeve [1]
The total number of packages completed was 41 and with 60 moustraps per package so 41 x 60 = 2460. Of these, 52 traps were from the previous shift and 34 were rejects so 2460-52-34 = 2374 produced + 24 in the last unsealed package = 2374 +24 = 2398.
