Which is a better approximation of the square root of20, 4.5 or 4.47

4.47

Step-by-step explanation:

Given :

To Find : Which is a better approximation

Solution:

20 lies between two perfect squares i.e. 16 and 25

Square root of 16 = 4

Square root of 25 = 5

So, Square root of 20 must lie between 4 and 5

Using calculator

The

Hence a better approximation of the square root of 20 is 4.47.

tigers

step-by-step explanation:

cougars 12/10 (12-10 = 2)

bobcats 20/10 (20-10 =10)

bulldogs 8/5 (8-5 =3)

tigers 3/5 (3-5 =-2)

faster, im not sure why but i know it is faster
