Răspuns:

21. a) (-3)^8:(-3)^5:(-3)^2= (+3)^3:(-3)^2=(-3)^1

b) (+7)^20:(+7)^7:(+7)^6= (+7)^7

c) (-23)^6:(-23)^0:(-23)^4= (-23)^6:1: (-23)^4=(+23)^2

d) (-4)^11:(-4)^11:(-4)^0= (+4)^0:(-4)^0= (+1)^1

e) (-107)^9:(-107)^3:(-107)^4= (+107)^6:(-107)^4=(-107)^2

f)x^m:x^2:x^3= x^m-2-3

22.

b)(+9)^4=(+9)^6:(+9)^2

c)(-3)^8=(+3)^13:(-3)^5

d) (+4)^5=(+4)^5:(+4)^0

e) (-13)^4=(-13)^5: (+13)^1

f) 11^5=11^7:11^2

g) (-5)^7= (+5)^9:(-5)^2

h) (-10)^0= (+10)^5: (-10)^5
