What is the square root of 5 times the square root of 60?

##sqrt(5)xxsqrt(60) = 10sqrt(3)##
##color(red)(sqrt(5))xxcolor(blue)(sqrt(60))##
##color(white)(XXX)=color(red)(sqrt(5))xxcolor(blue)(sqrt(2^2xx5xx3))##
##color(white)(XXX)=color(red)(sqrt(5))xxcolor(blue)
(2xxsqrt(5)xxsqrt(3))##
##color(white)(XXX)=color(red)(sqrt(5))xxcolor(blue)(sqrt(5))xx2sqrt(3)##
##color(white)(XXX)=5xx2sqrt(3)##
##color(white)(XXX)=10sqrt(3)##
