Answer 1

Explicație pas cu pas:

1.

a)27^22=9^33

(3^3)^22=(3^2)^33

3^66=3^66

b)1437^2017= 2017:4=54rest 1

1437^2017= ultima cifra este 7

2.

a)(2^5*2^9*2):2^13

(2^5+9+1):2:13

2^15:2^13=2^2

b)3^40:[3^38+(3^19)^2+(4^1-1)^38]=

3^40:[3^38+3^38+(4-1)^38]=

3.

a) (3^5)^×=(3^2)^5*3^2*3^3

(3^5)^×=3^10*3^2*3^3

(3^5)^×=3^10+2+3

(3^5)^×=3^15

×=3^15:3^5

×=3^10
