Answer 1

1) a) 1½ +2¼ - ⅔ *1,5 / 5 - 3 1/7 * 7/11 = 1 2/4 + 2 ¼ - 1 / 5 - 1 = 3¾ -1 / 4 = 2¾ / 4 = 11/16

2) a) -√48 = - 4√3

b) 1/4²= 1/16

c) 299⁰ = 1

d) (-⅕)³ = -1/125

e) ∛1 64/61 = ∛125/64 = 5/4

f) 6⁻³ : 6⁻¹ = 1/216 :1/6 = 36

3) 3+2√3 / 2√3 - 3 = (3+2√3 / 2√3 -3) * (2√3+3 / 2√3+3) = 9+12√3+12 / 12-9 = 21 + 12√3 / 3 = 7 + 4√3

4) 20*26 -19*25=520-475=45 lat

6) 2,3,5

 

1) 1⅔ - 14/6 - 21/6 / 3  : 5/12 - 10/12 = 1⅔ -(-7/6 : 3) : (-5/12) = 1⅔ + 7/2 : -5/12 = 1⅔ + 42/5 = 151/15

b) 1/8 *16 / 33554432 = 2/ 33554432 = 0,0000000596

2) √12 *√3 = √36 = 6

b) 1/-6 = -⅙

c)7⁰ = 1

d) (-⅔)⁴ = 16/81

e) ∛64/27 = 4/3

f)125 * 1/125 = 1

3) √3-1 /  4- 2√3 = √3 -1 /4-2√3 * 4+2√3 / 4+2√3= 4√3 -4+6-2√3 / 16- 6 = 2√3+2/10

4) 22*24 - 23*21 = 528 - 483 = 45 lat

5)2,3,5,7
