Answer 2

Answer:

a) 2 digits

b) 3 digits

c) 3 digits

d) 2 digits

e) 3 digits

f) 4 digits

Step-by-step explanation:

a) There are 4 digits in the number.

Therefore number of digits in the

square root

= n/2

= 4/2

= 2 digits

b) There are 5 digits in the number.

Therefore number of digits in the

square root

= n+1/2

= 5+1/2

= 6/2

= 3 digits

c) There are 6 digits in the number.

Therefore number of digits in the

square root

= 6/2

= 3 digits

d) There are 3 digits in the number.

Therefore number of digits in the

square root

= 3+1/2

= 4/2

= 2 digits

e) There are 6 digits in the number.

Therefore number of digits in the

square root

= 6/2

= 3 digits

f) There are 7 digits in the number.

Therefore number of digits in the

square root

= 7+1/2

= 8/2

= 4 digits
