What is the simplified form of -\left(14x\right)^0y^{-7}z
The simplified form of -\left(14x\right)^0y^{-7}z is -1yz^{-7}
(-m)^-3n if m=2 and n=-24
Substituting m=2 and n=-24 into (-m)^-3n, we have (-2)^-3(-24).
First, we calculate the value of (-2)^-3:
(-2)^-3 = -1/(-2)^3 = -1/(-8) = 1/8
Next, we substitute back into the expression:
(1/8)(-24) = -24/8 = -3
Thus, when m=2 and n=-24, the expression (-m)^-3n equals -3.
