DETERMINE AS POTENCIAS (-7) ELEVADO A -3 =
determine as potencias 7/4 elevado a 0 =
determine (0,8) elevado a -2 =
determine as potencias (1,2)elevado a -1 =
determine as potencias (0,001)elevado a -1 =

Answer 1

$(-7)^{-3} = \frac{1}{(-7)^3} = \frac{1}{343} \\ (7/4)^0 = 1 \\ 1,2^-1= \frac{10}{12} \\ 0,0001^-1 = (10^{-4})^{-1}=10^{4}$

Answer 2

15^-2= 0,0044 -7^-3 = 0,0029 7/4^0= 1 0,8^-2 = 1,5625 1,2^-1 = 0,8333 0,001^-1 = 1000,00
