oblicz

(2,5)^-1

(0,4)^-2

(1,25)^-1

(-10)^-5

(-4)^-2

(-2)^-3

(-0,1)^-5

(-0,02)^-4

Answer 1

(2,5)^-1=(5/2)^-1=2/5

(0,4)^-2=(10/4)^2=100/16

1,25)^-1=(5/4)^-1=4/5

(-10)^-5=(-1/10)^5=-1/100000

(-4)^-2=(-1/4)^2=1/16

(-2)^-3=(-1/2)^3=-1/8

(-0,1)^-5=(-10)^5=-100000

(-0,02)^-4=(-50)^4=6250000

Answer 2

(2,5)⁻¹=(2 ½)⁻¹=(5/2)⁻¹=(2/5)¹=2/5

(0,4)⁻²=(10/4)²=(5/2)²=25/4=6 1/4 

(1,25)⁻¹=(1 25/100)⁻¹=(1 1/4)⁻¹=(5/4)⁻¹=(4/5)¹=4/5 

(-10)⁻⁵=(-1/10)⁵=-0,00001

(-4)⁻²=(-1/4)²=1/16

(-2)⁻³=(-1/2)³=-1/8

(-0,1)⁻⁵=(-1/10)⁻⁵=(-10/1)⁵=-100000/1=-100000

(-0,02)⁻⁴=(-100/2)⁴=50⁴=6250000
