Question

Find the square root of 529 by finding the units and tens digit​

Answer 1

Answer:

23

Step-by-step explanation:

okay so..

20^2 = 400

30^2 = 900

529 lies between them

therefore, ten's digit = 2

25^2 = 625

so, units digit has to be less than 5

now, squares ending with 9 can only have either 3 or 7 in their square root's units place

Therefore, answer is 23.

Answer 2

Answer:

$\sqrt{529} = 23$

Step-by-step explanation:

At ones place the digit 9 we know that 3² =9 and 7²= 49

threfore in the sqiare root of 529,at units place of nimbee will be 3 or 7.Now if we leave the two figits from right we get 5.

Again we have to check the squares we know that 2²=4 and 3²=9 and 2² 5 3².Threforw taking the perfect square closet to 5 we take the digit 2 .Thus our square root is 23(check 23×23=529)
