Question

2^2*5^2-2^2÷{3*4^3-3*[3^3*2^2-5^2*(5^2*3-3^2*2^3)]



​

Answer 1

^ inseamna la puterea  

* inseamna ori

÷ inseamna impartit

2^2*5^2-2^2÷{3*4^3-3*[3^3*2^2-5^2*(5^2*3-3^2*2^3)]=

=4x25-4÷{3*64-3*[27*4-25*(25*3-9*8)]}=

=100-4÷{192-3*[108-25*(75-72)]}=

=100-4÷[192-3*(108-25*3)]=

=109-4÷[192-3*(108-75)]=

=109-4÷(192-3*33)=

=109-4÷(192-99)=

=109-4÷94=

=109-$\frac{4}{94}$

=109-$\frac{2}{47\\}$

PS sunt foarte obosit, scuze daca am gresit la calcule
