Answer 1

( √ 12 1/4) =√49/4=7/2=3  1/2

√4 21/25=√121/25=11/5=2 1/5

√ 1 7/9=√16/9=4/3= 1 1/3

√ 4 25/36= √169/36= 13/6= 2 1/6

 

 √ 1,21 =1,1

√ 2,25 =1,5

√2,89=1,7

√ 6,25=2,5

√1,44=1,2

 

15 5/8 =∛125/8=5/2=2 1/2

1 61/64 =∛125/64=5/4= 1 1/4

4 17/27 =∛125/27=5/3=1 2/3

2 93/125 =∛263/125=7/5=1 2/5

3 3/8=∛27/8= 3/2= 1 1/2

 

 

 0,000125=∛0.05

, 0,000064=∛0,04

, 0,000000008=∛0,002
