Come si semplifica #sqrt (49x ^ 5) #?
Risposta:
#sqrt(49x^5) =7x^2sqrt(x)#
Spiegazione:
#sqrt(49x^5) = sqrt(7^2*(x^2)^2*x)#
#color(white)("XXX")=sqrt(7^2)*sqrt((x^2)^2)*sqrt(x)#
#color(white)("XXX")=7x^2sqrt(x)#
#sqrt(49x^5) =7x^2sqrt(x)#
#sqrt(49x^5) = sqrt(7^2*(x^2)^2*x)#
#color(white)("XXX")=sqrt(7^2)*sqrt((x^2)^2)*sqrt(x)#
#color(white)("XXX")=7x^2sqrt(x)#
