Question

(x-273)+(1+3+5....+2015)=0

 

Answer 1

( x - 273 ) + ( (1+2015) x 1008 : 2 )  ) = 0

x - 273 + 1016064 = 0

x= 273 + 1016064 + 0 = 1016337

Answer 2

(x - 273) + (1 + 3 + 5 + ... + 2015) = 0

(x - 273) + [(1 + 2015) x 1008 : 2] = 0

x - 273 + 1016064 = 0

x = 273 + 1016064 + 0 

x = 1016337

Vậy x = 1016337

Answer 3

(x-273)=-(1+3+5+...+2015)

x-273=-2016.1008:2=1016064

x=1016064+273=1016337
