Answer 1

a) 3√5+√5-6√5 => 3-6√5 => -3√5

b)-4+∛5+2∛5-4 => -4-4+2³√5 => -8+2³√5

c)√50+√18-√8 => √5².2+√3².2-√2².2 => 5√2+3√2-2√2 => 6√2

d)2√27-5√12 => 2.√3².3 - 5.√2².3 => 2.3√3 -5.2√3 => 6√3 - 10√3 => -4√3

e)4√63-√7 => 4√3².7 - √7 => 4.3√7 -√7 => 12 √7-√7 => 12

f)√12+√75+√108 => √2².3 +√5².3 +√6².3 => 2√3 +5√3 +6√3 => 13√3
 
g)∛5·∛6 => ³√5.6 => ³√30

h)√2·√8 => √2.8 => √16 => 4

i)√2·√6·√3 => √2.6.3 => √36 => 6

j)∛4·∛6= ³√4.6 => ³√24 

j)√5·(1+√5) => √5 +²√5 => 5+√5
 
l)√49.√25 => 7.5 => 35

m)4.√2 => 4√2

n)7√3 => 7√3

o)√5.√2 => √5.2 => √10

p)7√3.√5 => 7.√3.5 => 7√15

q)(√15)² =>  15

r)(3√7)² => 9.7 => 63
