Conner and Jana are multiplying (3568)(39610).
NARA [144]

Step-by-step explanation :

Dado que Conner y Jana se multiplican (3568)(39610). El trabajo de Conner El trabajo de Jana (3568)(39610) = 35 + 968 + 10 = 314618 (3568)(39610) = 35⋅968⋅10 = 345680 ¿Es correcto cualquiera de ellos?

Jana y Conner están multiplicando dos números dados. Así que la pregunta es

                                 3568 x 39610

                                  0000

                                3568x

                            21408xx

                          32112xxx

                        10704xxxx

                --------------------------------------

                           141328480

Así que la respuesta correcta es 141328480.

También los números se pueden agrupar como

      3568 = 3000 + 500 + 60 + 8

    39610 = 30000 + 9000 + 600 + 10

Después de agrupar multiplicando ambos términos obtenemos la respuesta requerida.

Así que ninguno de los dos tiene la respuesta correcta.
