Question

please solve number 1 and 2​

Answer 1

Step-by-step explanation:

1. This shows that 26 Square is less than 740 by 64
2. So, the least number subtracted from 740 is 64

ans= 64

• (b) 14 should be subtracted from 1535 to make it a perfect square

ans= 14

• (c) 5 should be subtracted from 7926 to make it a perfect square.

ans = 5

1. (2a) 26 square is greater than 708 and 708 is greater than 27 square
2. So now the required number that is to be added is 27 square - 708
3. The number is 729 - 708 that is 21

there after the number that is to be added to 708 to make it a perfect square is

• (2b) we observe here that 42 square is greater than 1840 and 1840 is greater than 43 square
• the required number is 43 square - 1840
• so now we get 1849 - 1840 that is 9

ans= 9

• (2c) first we will find the square root of 7 926

• after finding we get the remainder as 5 and the square as 89
• now we observe that 89 square is larger than 7926 and 7926 is larger than 89 square
• now the required number is 90 square minus 7926
• 8100 - 7926
• That is = 174

HOPE IT HELPS YOU ☺
