Answer 1

2) Calcule.

a) √5 • √2 = √10

b) ⁴√2 • ⁴√8 = ⁴√16 = 2

c)√2 • (√7+2) = √14+2√2

d)³√5 • ³√6 = 3³√30

e)√2 • √8= √16 = 4

f))√2 • √6 • √3= √36 = 6

g) ³√4 • ³√6= ³√24 = 2³√3

h)√5 • (1 + √5)= √5+√25 = √5+5

i) 30√15 ÷ 5√3=

6√15.√3 =

6√45 =

6.3√5 =

18√5

j)√12 ÷ √3= √4 = 2

k)√50 ÷ √2= √25 = 5

l)√49 = 7/5

√25

m) (√7 + √3)²=

(√7)²+2(√7)(√3)+(√3)²

7+2√21+3

10+2√21
