8) Find the smallest number that must be added to 18625 to make it a
perfect square . Also find the square root of the number so obtained​

Answer 1

Answer:

144

Step-by-step explanation:

Just try it with trial and error method.

${140}^{2} = 19600$

So the answer will be lesser than 140.

${137}^{2} = 18769$

Just near to the answer but we will check for 136 also.

${136}^{2} = 18496$

The square of 136 is lesser than the given number and so 18769 - 18625

= 144 will be the answer.

Hope it helped you .......
