a) 2√2-8√2=-6√2

b) -4√2+2√3=-2√3

c) -24√5+9√5=-15√5

d) -7√6+7√6=0

f) 6√5-12√5=-6√5

6.

a) x=-2√2

y=-14√2

x+y;x-y

(-2√2)+(-14√2)=-2√2-14√2=-16√2

(-2√2) -(-14√2) =-2√2+14√2=12√2

b) x=√3

y=-2√3

x+y;x-y

√3+(-2√3)=√3-2√3=-√3

√3-(-2√3)=√3+2√3=3√3

c) x=-9√5

y=12√5

x+y;x-y

(-9√5)+12√5=-9√5+12√5=3√5

(-9√5)-(+12√5)=-9√5-12√5=-21√5

d) x=2√6

y=-4√6

x+y;x-y

2√6+(-4√6)=2√6-4√6=-2√6

2√6-(-4√6)=2√6+4√6=6√6
