Question

Imi spuneti si mie plz!!!
1. (8putere37 • 81putere25) : (16putere27 • 27³³)=?
2. 2¹ • 2² • 2³ • 2⁴ • ... • 2putere45=?
3. 1+2+3+...+73=?

Answer 1

3. Suma lui Gauss: 1+2+3+...+n=n(n+1)/2
73*74/2=73*37=2701

2. 2^(1+2+3+...+45)=2^(45*46/2)=2^(45*23)=2^1035

1. [(2^3)^37* (3^4)^25]:[(2^4)^27*(3^3)^33]=
=(2^111*3^100)/(2^108*3^99)=
=2^3*3=
=8*3=
=24
