Question

Calcula "a" Si: (7/4)5 × (7/4)7 × (7/4)4= (7/4)ª

Answer 1

Respuesta:

a = 11,8304

Explicación paso a paso:

(7/4)5 × (7/4)7 × (7/4)4= (7/4)ª

35/4*49/4*28/4 = (7/4)ª

12005/16=(7/4)ª

ln(12005/16) = ln(7/4)ª

ln(12005/16) = aln(7/4)

a = ln(12005/16)/ln(7/4)

a = 11,8304

comprobando

12005/16=(7/4)^11,8304

750,3125 = 750,3041 difiere un poco por las cifras significativas
