Answer 1

Răspuns:

Explicație pas cu pas:

a) (-1/3)^3 = - 1/27

b) 1 x (-27/8) = - 27/8

c) (-1/7)^1 = -1/7

d) (0,2)^2 = 0,04

e) (1,5)^2 = 2,25

f) (0,5)^(-2) = 4

Answer 2

a) (-1/3) × (-1/3)^2 = Se aduna puterile => 1+2=3 => (-1/3)^3

b) (-2/-3)^0 × (-3/-2)^3 = Se aduna puterile 0+3=3 => (-2/-3)^3

c) (-1/7)^4 ÷ (-1/7)^3 = Se scad puterile 4-3=1 => (-1/7)

d) (0,(2))^7 ÷ (0,(2))^5 =Se scad puterile 7-5=2 => 0,(2))^2 = (2/9)^2

e) (1,(5))^5 ÷ (1,(5))^3 = Se scad puterile 5-3= 2 => (1,(5))^2 = (14/9)^2

f) [(0,5)^2]^-1 = Puterile se inmultesc 2×(-1)=-2 => (0,5)^-2 = (5/10)^-2 = (10/5)^2

SPER CA TE AM AJUTAT :))
