(½+⅔)²-7/12=¼+49/36+4/9-7/12= 9/36+49/36+16/36-21/36 = 53/36 =
1 17/36
(1⅔)²*(3/5)³=(5/3)²*(3/5)³=25/9*27/125 = 3/5
1 17/36
(1⅔)²*(3/5)³=(5/3)²*(3/5)³=25/9*27/125 = 3/5
(½+⅔)² - 7/12 = 1/4 +4/9 + 4/6 = 1/4 + 4/9 + 6/9 = 1/4 + 10/9 = 9/36 + 40/36 = 1 cała i 13/36
(1 2/3 )² * (3/5)³ = (5/3)² * (3/5)³ = 25/9 * 27/125 = 3/5
mam nadzieje, że pomogłam :)
