Explicație pas cu pas:

2.

a)

4,7^9 * 4,7^15 = 4,7^(9+15) = 4,7^24

b)

2,3^18 : 2,3^12 = 2,3^(18-12) = 2,3^6

c)

(3.15^4)^6 = 3,15^4*6 = 3,15^24

d)

1,5^4 * 0,6^4 = (1,5*0,6)^4 = 0,9^4

3.

(3,6^2 : 7,2 + 64 : 0,05)*3^3 + 2019^0

= (12,96 : 7,2 + 1280)*27 + 1

= (1,8 + 1280)*27 + 1

= 1281,8 * 27 + 1

= 34608,6 + 1 = 34609,6
