Answer:

square root of 24.5 is 4.94974747, but a better approximation would be 5 and approximation of square root of 4.47 would be 2

Explanation:

25 square rooted is 5, so square root of 24.5 is approximately the same. 4 squared is 2, which the square rooted of 4.47 would be approximately the same

Answer:

4.47

Explanation:

What square roots are having √20 in between them?...

√16 = 4 √20 ≈ a number between 4 and 5 √25=5

║ ║ ║

16 is 4 away from 20 25 is 5 away form 20

so √20 is closer to √16 (=4)

so a better approximation is the one closer to 4

so is 4.47
