The number #845# is divisible by 5. It equals #5*169#

#color(red)(sqrt845#

#= sqrt(5*169)#

#= sqrt(5)*sqrt(169)# (In general, #color(blue)(sqrt(a*b) = sqrt(a)*sqrt(b)#)

#= sqrt(5)*13# (Because #sqrt169 = 13#)

#= color(green)(13*sqrt(5)#

#sqrt845# in the Simplest Radical form is #color(green)(13*sqrt(5)#
