(-10)x^{-5}

(-4)x^{-2}

(-2)x^{-3}

( - 2/3)x^{-2}

BŁAGAAAAAAAAAAM

x^ .. oznacza wykładnik całkowity ujemny

Answer 1

(2,5)x^{-1} = (5/2)⁻¹ = (2/5)¹ = 2/5

 

(0,4)x^{-2} = (4/10)⁻² = (10/4)² = 100/16 = 25/4 = 6 1/4

 

(1,25)x^{-1} = (5/4)⁻¹ = 4/5

 

(-10)x^{-5} = (-10)⁻⁵ = (-1/10)⁵ = -1/100000

 

(-4)x^{-2} = (-4)⁻² = (-1/4)² = 1/16

 

(-2)x^{-3} = (-2)⁻³ = (-1/2)³ = -1/8

 

( - 2/3)x^{-2} = (-3/2)³ = -27/8 = -3 3/8

 

(- 1/5)x^{-3} = (-5)³ = -125

 

(3 1/3)x^{-4} = (10/3)⁻⁴ = (3/10)⁴ = 81/10000

 

(-1,2)x^{-1} = (-12/10)⁻¹ = (-10/12)¹ = -10/12

 

(-0,1)x^{-5} = (-10)⁵ = -100000

 

(-0,02)x^{-4} = (-2/100)⁻⁴ = (-100/2)⁴ = 100000000/16 = 6250000

Answer 2

załacznik ;)

 

  \w przed ostatnim ma bbyć 10 000 bo sie pomyliłem .
