Question

va rog ajutati ma va dau ce vreti voi promit!!!​

Answer 1

a)

2^4×2^3×2=

2^4×2^3×2^1=

2^4+3+1=

2^8

b)

(4/5)^3×(4/5)^2×(4/5)^-7=

(4/5)^3+2+(-7)=

(4/5)^5-7=

(4/5)^-2

c)

(-3,5)^4×(-3,5)^2×(-3,5)^-3=

(-3,5)^4+2+(-3)=

(-3,5)^6-3=

(-3,5)^3

d)

{[(2/3)^2]^3}^4=

(2/3)^2×3×4=

(2/3)^24

Answer 2

a) 2⁴ · 2³ · 2 = 2⁴⁺³⁺¹ = 2⁸

b) (4/5)³·(4/5)²·(4/5)⁻⁷ = (4/5)³⁺²⁻⁷ = (4/5)⁻²

c) (-3,5)⁴·(-3,5)²·(-3,5)⁻³ = (-3,5)⁴⁺²⁻³ = (-3,5)³

d) {[(2/3)²]³}⁴ = (2/3)²ˣ³ˣ⁴ = (2/3)²⁴
