Answer 1

Odpowiedź:

1.

a)

8³ * 8^4 = 8^7

b)

4² * 4^1 * 4^9 = 4³ * 4^9 = 4^12

c)

12^5 : 12² = 12^7

d)

(6^5)³ = 6^15

2.

a)

5³ * 20³ = (5 * 20)³ = 100³ = 100 00 00

b)

(3/4)^5 * (1 1/3)^5 = (3/4 * 4/3)^5 = 1^5 = 1

c)

0,7² * (-10)² = [0,7 * (-10)]² = (-7)² = 49

d)

12^4 : 4^4 = (12 : 4)^4 = 3^4 = 81

e)

8^5 : (-8)^5 = (-1)^5 = -1

3.

a)

(9³)² : 3^4 = [(3²)³]² : 3^4 = (3^6)² : 3^4 = 3^12 : 3^4 = 3^8  

b)

125^7 : 25³ = (5³)^7 : (5²)³ = 5^21 : 5^6 = 5^15

c)

4^10 + 4^10 + 4^10 + 4^10 = 4 * 4^10 = 4^11

d)

(9³)² : 3^4 = [(3²)³]² : 3^4 = (3^6)² : 3^4 = 3^12 : 3^4 = 3^8
