Answer 1

a^-1 * a ^3 * a ^-3 = a⁻¹⁺³⁻³ = a⁻¹ = 1/a

 x^-2: x^-1= x⁻²⁺¹ = x⁻¹ = 1/x

 (b^3)^5= b¹⁵

 (x^2y^3)^-2= x⁻⁴y⁻⁶

 2. (0,2)^-1= (2/10)⁻¹ = 10/2 = 5

 (-5/2)^-2= (-2/5)² = 4/25

 -(2^-2)^-3= -(2⁶) = -64

 (2^-2;2^-3)^-4= (2¹)⁻⁴ = 2⁻⁴ = (1/2)⁴ = 1/16

 3^-2*(1/9)^-2*27^-2= 3⁻² * 9² * 27⁻² = 3⁻² * 3⁴ * 3⁻⁶ = 3 ⁻⁴ = (1/3)⁴ = 1/81

[(1/3)^-5;(1/3)^-2];(3^6*3^-5= (1/3)⁻³ : 3¹ = 3³ : 3¹ = 3² = 9

 

3. uporządkuj liczbe malejaco

(1/2)^-3 = 2³ = 8

2^4 = 16

(-1/4)^-4 = (-4)⁴ = 256

/16 ??????????

300000 = 3 * 10⁵

0,00005 = 5 * 10⁻⁵

0,5*10^-5 = 5 * 10⁻⁴
