Explicație pas cu pas:
1.
a) (1/5)^2 = 1/25
b) (2/3)^3 = 8/27
c) (2 1/2)^2 = (5/2)^2 = 25/4 = 6 1/4 (6 intregi si 1.4)
d) (1 1/10)^3 = (11/10)^3 = 1331/1000 = 1 331/1000 (1 intreg si 331/1000)
2.
a) (12/15)^0 = 1
b) (3/5)^1 = 3/5
c) (1/10)^5 = 1/100000
d) (1 1/2)^4 = (3/2)^4 = 81/16 = 5 1/16 (5 intregi si 1/6)
e) (10/3)^6 = 1000000/729 = 1371 541/729 (1371 intregi si 541/729)
f) (7/4)^1 = 7/4 = 1 intreg si 3/4
g) (1 3/5)^2 = (8/5)^2 = 64/25 = 2 intregi si 14/25
h) (2 3/4)^3 = (11/4)^3 = 1331/64 = 20 intregi si 51/64
i) (0/7)^? = 0 (nu se vede exponentul, dar oricare ar fi, rezultatul este 0)
j) (2/1)^8 = 2^8 = 256
