You need to decouple your root:

#7sqrt(6*100)#
#7sqrt(6*10*10)#

As we have a squared number inside a square root, we can take it out, like this:

#7*10sqrt(6*10)#
#70sqrt(60)#

However, we can keep on simplifying:

#70sqrt(4*15)#
#70sqrt(2*2*15)#
#70*2sqrt(15)#

Final answer would be #140sqrt(15)#
