Question

10. What least number must be subtracted from 176 to make it a perfect square?
​

Answer 1

Answer:

The answer is 7. Because if we subtract 176-7= 169 so √169= 13.

Answer 2

Given - A number 176

Find - Least number to be subtracted from 176 to make it a perfect square.

Solution - Nearest perfect square number before 176 is 169.

Let the least number to be subtracted be x.

176 - x = 169

x = 176 - 169

x = 7

Thus, 7 is the least number that can be substracted from 176 to make it a perfect square. It will be the perfect square 169 of number 13.
