Question

Zadanie 4 i 5.

Answer 1

ZADANIE 4

a)

(-4)⁴=256

-4⁴= -256

-(0,4)²= -(4/10)²= -(2/5)²= -4/25

(-0,4)²=(-4/10)²=(-2/5)²=4/25

(-2)³=-8

-2³=-8

 

b)

5²/8=25/8=3 1/8

5/8²=5/64

(-5/8)²=25/64

-(5/8)²= -25/64

-5²/8=-25/8= -3 1/8

5/-8²= -25/64

 

c)

15²=225

(1,5)²=2,25

-15²= -225

(-15)²=225

-(1,5)²= -2,25

(-1,5)²=2,25

 

ZADANIE 5

ustawione w kolejności z obliczeniami:

(-5)²=25

(-1/2)²=1/4

-(-1/3)³=-(-1/27)=1/27

(-1/3)³= -1/27

-(1/2)²=-1/4

-5²=-25
