Помогите решить,а то за лето все забор

(а)²= а*а

а) (1/7)²= 1/49

б) (1/4)²= 1/16

в) (3/5)²= 9/25

г) (4/3)²= 16/9= 1 7/9

(а)³=а*а*а

а) (1/4)³=1/64

(2/5)³= 8/125

(3/10)³= 27/1000

(4/3)³= 64/27= 2 10/27

(а/в)ⁿ=аⁿ/вⁿ

№6

(1/7)²=1/49; (1/4)²=1/16; (3/5)²=9/25; (4/3)²=16/9=1 7/9

№7

(1/4)³=1/64; (2/5)³=8/125; (3/10)³=27/1000=0,027; (4/3)³=64/27=2 10/27.
