b) 7 x 7 x 7 x 7 = [ ] [ ]

c) (-9) x (-9) x (-9) = [ ]

d) 0,8 x 0,8 x 0,8 x 0,8 = [ ]

e) 8 =

f) (1/5) x (1/5) x (1/5) x (1/5) x (1/5) x (1/5) = [ ]

2. Uzupełnij.

a) 2 [ ] = 16

b) 3 [ ] = 27

c) 8 [ ] = 8

d) [ ] 2 = 4

e) [ ] 2 = 9

f) [ ] 4 = 256

g) 17 [ ] = 1

h) 5 [ ] 625

i) (1/2) [ ] = 1/4

3. Zapisz iloczyny, używając potęg.

a) 2 x 2 x 2 x 3 x 3 x 3 = [ ]

b) (-4) x (-4) x 3 x 3 x (-4) = [ ]

c) (-2) x 1/2 x (-2) x 1/2 = [ ]

d) 5 x 3 x 3 x 5 x 2 x 5 = [ ]

e) (1 cała i 1/3) x (1 cała i 1/3) x (4/3) x (4/3) x (4/3) = [ ]

4. Uzupełnij.

a) 7 [ ] = 1

b) 8 [ ] = 512

c) (-2) [ ] = -32

d) 0,5 [ ] = 0,125

e) (1/ [ ] ) 2 = 1/25

f) (7/11) [ ] = 343/1331

g) ( [ ] / 6 ) [ ] = 9/36

h) ( [ ] / 2 ) [ ] = 9

i) ( [ ] / [ ] ) [ ] = 1

Wytłumaczenie :

x - mnożenie

[ ] - pole, w którym trzeba wpisać liczbę
