Question 3.
Find the least number that is to be subtracted from 4000 to make it perfect square
Solution:
Square root of 4000 by
Division Method:

∴ The least number 31 should be subtracted from 4000 we will get a perfect square number4
∴ 4000 – 31 = 3969
= 3969‾‾‾‾‾√=63×63‾‾‾‾‾‾‾√ = 63

Question 4.
Find the length of the side of a square whose area is 4489 sq.cm.
Solution:
Area of a square (A) = 4489 sq.cms
A = s2
s2 = 4489
s = 4489‾‾‾‾‾√=67×67‾‾‾‾‾‾‾√ = 67cms.
∴ The side of a square (s) = 67cms.

Question 5.
A gardener wishes to plant 8289 plants in the form of a square and found that there were 8 plants left. How many plants were planted in each row?
Solution:
No. of plants are planted = 8289 If 8289 plants are planted in a square shape, 8 plants are left.
Then remaining plants = 8289 – 8 = 8281

∴ No. of plants for each row = 91
∴ 8281 plants are planted in a square shape then no. of plants are planted for each row = 91

Question 6.
Find the least perfect square with four digits.
Solution:
The smallest number of 4 digits = 1000

∴ 24 should be added tö 1000 then 1000 + 24 = 1024
∴ The smallest 4 digited perfect square number is 1024.
[∵ 1024‾‾‾‾‾√ = 32]

Question 7.
Find the least number which must be added to 6412 to make it a perfect square?
Solution:

∴ The least number 149 should be added to 6412 then we will get a perfect square number.
∴ 6412 + 149 = 6561
∴ 6561‾‾‾‾‾√=81×81‾‾‾‾‾‾‾√ = 81

Question 8.
Estimate the value of the following numbers to the nearest whole number
(i) 97‾‾‾√
(ii) 250‾‾‾‾√
(iii) 780‾‾‾‾√
Solution:
ï) 97‾‾‾√ , 97 lie between the perfect
square numbers 81 and 100.
∴ 81 <97< 100
92 < 97 < 102
=9 < 97‾‾‾√ < 10
∴ 97‾‾‾√ Is nearest to 10.
[∵ 97 is nearest to 100]

(ii) 250‾‾‾‾√, 250 lie between the perfect square numbers 225 and 256.
∴ 225 < 250 < 256
152 < 250 < 162
= 15 < 250‾‾‾‾√ <16
∴ 250‾‾‾‾√ is nearest to 16.
[ ∵ 250 is nearest to 256]

ii) 780‾‾‾‾√, 780 lie between the perfect
square numbers 729 and 784.
∴ 729 < 780 < 784
272 < 780 < 282
= 27< 780‾‾‾‾√ <28
∴ 780‾‾‾‾√ is nearest to 28.
[ ∵ 780 is nearest to 784]
