It is given that:

The square root of 225:

= √225

After using the prooerty of integer exponent:

As we know,

$\sqrt{a} = a^{1/2}$

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

= √225

$= 225^{1/2}$

= √225

= √(15x15)

= 15

Thus, the square root of 225 or √225 can be written as 15 option (B) 15 and option (C) are correct.
