Răspuns:

Explicație pas cu pas:

a) √147:√3=√(147:3)=√49=√7²=7

b) √72:√2=√(72:2)=√36=√6²=6

c) √125:√5=√(125:5)=√25=√5²=5

d) √112:√7=√(112:7)=√16=√4²=4

e) √(2⁵·3⁶):√(2·3²)=√(2⁵·3⁶:2·3²)=√(2⁴·3⁴)=2²·3²=4·9=36

f) √(7³.5⁵):√(7·5³)=√(7³.5⁵:7·5³)=√(7²·5²)=7·5=35

g) √11⁷:√11³=√(11⁷:11³)=√11⁴=11²=121

h) -√32:√2³=-√(32:2³)=-√(32:4)=-√4=-2

i) √24:(-√2·3)=-√[24:(-2·3)]=-√4=-2

j) -√864:√(2³·3)=-√[864:(2³·3)]=-√(864:24)=-√36=-√6²=-6

k) -√16⁴:√2⁴=-√(16⁴:2⁴)=-√(16⁴:16)=-√16³=-16√16=-16√4²=-16·4=-64

l) √125¹⁰:√25¹⁵=√(125¹⁰:25¹⁵)=√[(5³)¹⁰:(5²)¹⁵]=√(5³⁰:5³⁰)=√1=1
