How do you simplify #-11sqrt21-11sqrt21#?

Answer 1

#-22sqrt21#

We can work with the numbers outside of the square root because the square roots alone have the same value, so they can be disregarded.

So,

#-11color(red)(sqrt21)-11color(red)(sqrt21)#

Since square roots are equal,...

#-11-11#
#-22#

then redo our square root after that

#-22sqrt21#
