Answer 1

a) √2-4√2+2√2=

-4+2√2 = -2√2

b) 5√3 - 12√3 - 6√3=

+5-12-6√3

+5-18√3 = -13√3

c) 9√5 - √5 + 5√5=

9-1+5√5

14-1√5 = 13√5

d) -3√7-2√7-3√7=

-3-2-3√7 = -8√7

e) 10. ³√6-10³√6-9.³√6=

+10-10-9 ³√6 = -9 ³√6

F) √27 + √75=

3√3+5√3

+3+5√3 = 8√3

g) 2√7+√28=

2√7+1√7

+2+1√7 = 3√7

h √50-√98=

5√2-7√2

+5-7√2 =-2√2

i) -√12-6√3=

-2√3-6√3

-2-6√3 = -8√3

j) √20 - √45=

2√5-3√5

+2-3√5 =-√5
