Answer 1

Odpowiedź:

15 - 10       24 - 16

----------  +  ------------ = 5/15 + 8/45 = 15/45 + 8/45 = 23/45

25 - 10      18+27

(1/2 - 1/6)² + (1/6)² = (3/6 - 1/6)² + (1/6)² = 4/12 + 1/36 = 12/36 + 1/36 = 13/36

3² * (15 : 3)² = 3² * (5)² = 9 * 25 = 225

5 * (1/7 + 3/5)  = 3 i 5/7   =  5/7 + 3 = 3 i 5/7

5 * (1/7 + 3/5) = 5 * (5/35 + 21/35) = 5 * 26/35 = 26/7 = 3 i 5/7

5/7 + 3 = 3 i 5/7

(1/9 - 1/10)  : 3 = (10/90 - 9/90) : 3 = 1/90 * 1/3 = 1/270

1/27 - 1/30 = 30/810 - 27/810 = 3/810 = 1/270

(1/9 -1/10) : 3= 1/270    =    1/27 - 1/30 = 1/270

5²/3² = 25/9

(5/3)² = 25/9

5²/3²  = 25/9   =   (5/3)² = 25/9
