b) (1/3)^4 + (- 1/3 ) ^4 =

g) 3* (1/2)^0 +8* (-1/2)^4 =

i) (-0,1)^4*20 ^3-(-2) ^4 =

^ oznacza do potęgi

Proszę pomóżcie

Z góry dzięki

Answer 1

b)

(1/3)⁴ + ( - 1/3)⁴ = (1/3)⁴ + (1/3)⁴ =

 

= 2*(1/3)⁴  =

 

= 2 * (1/81) =

 

= 2/81

g)

 

3* (1/2)⁰ + 8 * ( - 1/2)⁴ = 3*1 + 8*(1/2)⁴ =

 

= 3 + 8 * (1/16) =

 

= 3 + 8/16 =

 

= 3 + 1/2 =

 

= 3,5

i)

 

( - 0,1)⁴ * 20³ - ( - 2)⁴  = (0,1)⁴ *8000 -  2⁴ =

 

= 0,0001*8000 - 16 =

 

= 0,8 - 16 =

 

= - 15,2

Answer 2

b) (1/3)^4 + (- 1/3 ) ^4 =
= 1/81 + 1/81 =
= 2/81

g) 3* (1/2)^0 + 8 * (-1/2)^4 =
= 3 * 1 + 8 * 1/16 =
= 3 * 2/4 =
= 3,5 

i) (-0,1)^4 * 20 ^3 - (-2)^4 =
= 0,0001 * 8000 - 16 =
= 0,8 - 16 =
= -15,2
