Answer 11

which 2 consequtive whole numbers does the square root of 55 lie between? explain how you determined these 2 whole numbers

Answer 12

The closest I know as an example is sqrt(10)

9 is the closest sqaure to 10, and sqrt(9) =3

so sqrt(10) = 3.something, which it is. Don't know how to get further with that trick though

Answer 13

*perfect sqaure to 10

Answer 14

we know that 7^2=49
we know that 8^2=64
Therefore the square root of 55 must be between 7 and 8 since 55 is between 49 and 64

Answer 15

i guess it can be a decimal aproxcimation
