Answer 1

a)√36/25=6/5 

bo (6/5)²=36/25

 

b)√9/121=3/11

bo (3/11)²=9/121

 

c)√81/400=9/20

bo (9/20)²=81/400

 

d)√225/196=15/14

bo (15/14)²=225/196

 

e)√100/49=10/7

bo (10/7)²=100/49

 

f)√16/289 =4/17

bo (4/17)²=16/289

 

g)√5⁴/₉=√49/9=7/3

bo (7/3)²=49/9 =5⁴/₉

 

h)√2²/₄₉ =√100/49 =√10/7

bo (10/7)²=100/49 =2²/₄₉

 

i)√1¹¹/₂₅ =√36/25=6/5

bo (6/5)²=36/25 =1¹¹/₂₅

 

j)√7¹/₉ =√64/9=8/3

bo (8/3)²=64/9

 

k)√3¹³/₃₆ =√121/36=11/6

bo (11/6)²=121/36

 

l)√5¹⁹/₂₅ =√144/25=12/5

bo (12/5)²=144/25=5¹⁹/₂₅

 

 

 

 

 

Answer 2

a) √36/25 = 6/5 = 1 1/5

b) √9/121 =  3/11

c) √81/400 = 9/20

d) √225/196 =  15/14 = 1 1/14

e) √100/49 = 10/7 = 1 3/7

f) √16/289 = 4/17

g) √5 4/9 = √49/9 = 7/3 = 2 1/3

h) √2 2/49 = √100/49 = 10/7 = 1 3/7

i) √1 11/25 = √36/25 = 6/5 = 1 1/5

j) √7 1/9 = √64/9 = 8/3 = 2 2/3

k) √3 13/36 = √121/36 = 11/6 = 1 5/6

l) √5 19/25 = √144/25 = 12/5 = 2 2/5

 

Powodzenia :)
