(3^11)^3:(3^11x3^19)=?
(7x7^19)^3:7^58=?
apropo ^ inseamna la putere..

Answer 1

( 2^37 :2^17)^2 :2^35= 32
(2^37-17)^2 : 2^35 =
(2^20)^2 : 2^35=
2^40 : 2^35 =
2^40-35=
2^5=32

(3^11)^3 : (3^11 x3^19)= 3^3=27
3^33: (3^11+19)=
3^33 : 3^30=
3^33-30=
3^3

(7 x 7^19)^3 : 7^58=49
(7^1+19)^3 :7^58=
(7^20)^3 : 7^58=
7^60 : 7^58=
7^60-58=
7^2=49
