Answer 1

Ответ:

Пошаговое объяснение:

1) ( 3/5 $)^{2}$ =3 * 3 / 5 * 2 = 9/10

( 1 1/3$)^{2}$ = ( 4/3$)^{2}$ = 4 * 4 / 3 * 3 = 16/9 = 1 7/9

( 2 1/2 $)^{2}$ = ( 5/2 $)^{2}$ = 5 * 5 / 2 * 2 = 25/4 = 6 1/4

2) ( 3/5 $)^{3}$ = 3 * 3 * 3 / 5 * 5 * 5 = 27/125

( 1 1/3$)^{3}$ = ( 4/3 $)^{3}$ = 4 * 4 * 4 / 3 * 3 * 3 = 64/27 = 2 10/27

( 2 1/2 $)^{3}$ = ( 5/2 $)^{3}$ = 5 * 5 * 5 / 2 * 2 * 2 = 125/8 = 15 5/8
