Răspuns:
Explicație pas cu pas:
a)
-3^2 = -9
5^2 = 25
0,9 = 9/10
-9/25 : 9/10 = -9/25 * 10/9 = -2/5
b)
-1 + 3/2 = -2/2 + 3/2 = 1/2
(1/2)^2 = 1/4
c)
-1 + 2/3 = -3/3 + 2/3 = -1/3
(-1/3)^3 = -1/27
d)
-0,1 = -1/10
(-1/10)^-2 = (-10)^2 = 100
5^0 = 1
100 + 1 = 101
e)
-1 + 3/2 = -2/2 + 3/2 = 1/2
(1/2)^-2 = 2^2 = 4
f)
-1 + 2/3 = -3/3 + 2/3 = -1/3
(-1/3)^-3 = (-3)^3 = -27
