Szczegółowe wyjaśnienie:
Zad 1.
a) 1,3^2 = (13/10)^2 = 169/100 = 1,69
- 1,3^2 = -169/100 = -1,69
(-1,3)^2 = 169/100 = 1,69
b) (-1)^15 = -1
-1^16 = -1
(-1)^34 = 1
Zad. 2
(1,4)^2 - (0,4)^2 = (14/10)^2 - (4/10)^2 = 196/100 - 16/100 = 182/100 = 1,82
Zad. 3
a)5^8 : 5^4 * 5^2 = 5^4 * 5^2 = 5^6
b) (0,4^5)^3 = (0,4)^15
c) = 9^14 : 9^2 = 9^12
Zad. 4
(-3)^5 ; -(1/3)^5 ; (1/3)^5 ; 3^5
Zad. 5
a) 3^7 * (1/9)^7 : (1/3)^4 = (3 * 1/9)^7 : (1/3)^4 = (1/3)^7 : (1/3)^4 = (1/3)^3
b) [tex]\frac{(1/4) ^9 : (5/16)^9}{(0,8)^7} = \frac{(1/4 * 16:5) ^9}{(0,8)^7} = \frac{(4/5)^9}{(4/5)^7} = (4/5)^2[/tex]
Zad. 6
a) 34 000 000 = 34 *10^6
b) 0,00000876 = 876 *10^-8
Liczę na naj :) :D
