Answer:
3) 21
4) between 6 and 7
5) 14
6) 7
7) 5
Step-by-step explanation:
3) √441 = 21
4) We write √40 to be the square root of 40, and can investigate between which two whole numbers it lies. The number 40 lies between 36 and 49 hence √40 lies between 6 and 7.
5) √184 to whole number
= 13.6 = 14
∴ √184 is equal to 14 round to a whole number
6) √45 to whole number is 7
=6.7 = 7
7) √27 to whole number is 5
=5.2 = 5
