A)
= 8^(-17+20) : 8^(-3)
= 8^3 : 8^(-3)
= 8^[3-(-3)]
= 8^[3+3]
= 8^6
____________

B)
= 9^(21-22) . 9^(-1)
= 9^(-1). 9^(-1)
= 9^(-1-1)
= 9^(-2)
__________
C)
= 1^(-21) . 1^(-22) . 1^43
= 1^(-21-22) . 1^43
= 1^(-43) . 1^43
= 1^(-43+43)
= 1^0
= 1
_________
D)
= 4^(9-11) : 4^17
= 4^(-2) : 4^17
= 4^(-2-17)
= 4^(-19)
_________
E)
= (-5)^[19.17]
= (-5)^323
___________
F)
(-19.49)^8 = (-931)^8
_________

G)
(-189/9)^7 = (- 21)^7
___________

a)8-¹⁷.8²⁰:8-³ = 8³:8-³ = 8⁶

b) 9-²²:9-²¹.9-¹ = 9-⁴⁴ = 1/9⁴⁴

c) 1-²¹.1-²².1⁴³ = 1-⁴³.1⁴³ = 1⁰ = 1

d) 4⁹:4¹¹:4¹⁷ = 4-²:4¹⁷ = 4-¹⁹ = 1/4-¹⁹

e) (-5-¹⁹)-¹⁷ = -5³²³

f) (-19)⁸.(+49)⁸ = 931⁸

g) (-189)⁷:(+9)⁷ = -21⁷

❤️ Espero ter ajudado ❤️
