Question

calculați: b)c)d) Va rog cat de repede! dau coroana!!! ​

Answer 1

sqrt(1 9/16)=sqrt(25/16)=5/4

sqrt(2 1/4)=sqrt(9/4)=3/2

sqrt(3 13/36)=sqrt(121/36)=11/6

sqrt(4 29/49)=sqrt(225/49)=15/7

sqrt(5 29/100)=sqrt(529/100)=23/10

sqrt(0,81)=sqrt(81/100)=9/10=0,9

sqrt(0,16)=sqrt(16/100)=4/10=0,4

sqrt(1,96)=sqrt(196/100)=14/10=1,4

sqrt(4,41)=sqrt(441/100)=21/10=2,1

sqrt(20,25)=sqrt(2025/100)=sqrt(3·3·225/100)=sqrt(3·15·3·15/100)=3·15/10=45/10=4,5

sqrt(2^4/3^6)=2^2/3^3

sqrt(3^4·5^6/7^2)=3^2·5^3/7

sqrt(12/3^3·4^3)=sqrt(1/3^2·4^2)=1/12

sqrt((3^2+4^2)/(7^2+24^2))=sqrt(25/625)=sqrt(1/25)=1/5
