Question

Medal and fan
which two square roots are used to estimate square root of 47

Answer 1

square root of 25 and 36
square root of 25 and 49
square root of 36 and 49
square root of 49 and 64

Answer 2

if you take the squares of each value you should and the square of 47 it should stand out

Answer 3

sqrt(47) = 6.9 so since sqrt(25) = 5 and sqrt( 36) is 6 that can not be the right choice and sqrt(49) =7 and sqrt(64) = 8 so again no good.

Answer 4

√36 < √47 < √49
