zadanie 3
a.(-6)² - 5 ² = 36 - 25 =11
b.(-2) ²:4 ² = 4 : 16 = 1/4
c.(-6) ²:(-3)3 = 36 : 9 = 4
d.4 3 -2*(-5) ² = 64 - 4 * 25 = 64 - 100 = 36
e.(-10)3 -2*(-15) ² = -1000 - 2* 225 = -1000 - 450 = -1450
f.-6 ²+(-5) ² = -36 +25 = -11
g.(-5)3 -(-3)5 = -125 + 243 = 118
h.12 ²:(-2)3 = 144 : (-8) = -18
i.2*(-3)3- (-8) ² = 2* (-27) - 16 = -54 - 16 =- 70
j. -14 ²+(-13) ²= - 196 + 169 = -27
zadanie 4
a. 1/2 *1/25 -(3/5) ² = 1/50 – 9/25 = - 17/50
b.2* (1/3) ²+7/9 = 2* 1/9 + 7/9 = 1
c.4/3*(-1/2)²- 2 0 = 4/3 * 1/4 - 20 = 1/3 -20 = -19 2/3
d,-(2/3)3+(-3/2) ² = - 4/9 + 9/4 = - 16/36 + 2 9/36 = -1 29/36
e. (3/5) ² -2*(1/2)3:2 1/4 -(-1)3 = 9/25 – 2/8 : 2 1/4 + 1 = 9/25 – 1/9 +1 = 81/225 – 25/225 +1 = 1 56/225
