Answer 1

Пошаговое объяснение:

( 1 1/3)2 * ( 3 1/16+0,75)=9 1/27

( 1 1/3)2=(4/3)^2=16/9

3 1/16+0,75=3 1/16+3/4=(49+12)/16=61/12

16/9*61/12=976/108=9 4/108=9 1/27

Answer 2

(11/3)2 * (3 1/16+0,75)

11 * 2/3 * (48+1/16 + 75/100) = 22/3
* (49/16 + 75/100) = 22/3 * (49 * 25/16 * 25 + 75 * 4/100 * 4) = 22/3 * (1225/400 + 300/400) = 22/3 * 1225 + 300/400 = 22/3 * 1525/400 = 22 * 1525/3 * 400 = 33550/1200 = 671 * 50/24 * 50 = 671/24 = 27/23/24 ~~ 27,958
