Why is it important to simplify radical expressions before adding or subtracting?
suppose you had:
sqrt(8)+sqrt(2)
if you simplify it:
2(2sqrt(2))+sqrt(2)
what would you be able to do?
4sqrt(2)+sqrt(2)
= 5sqrt(2)
sqrt(8)+sqrt(2)
if you simplify it:
2(2sqrt(2))+sqrt(2)
what would you be able to do?
4sqrt(2)+sqrt(2)
= 5sqrt(2)
