Answer 2

15 is the square root. Given: x²-225=0

To Find: Square root of x²-225=0

Solution: To find the square root of x²-225=0

Take 225 to the R.H.S

which will make it +225 from -225

x²=225 will come out as an answer

when we take ² of x on R.H.S x will become square root(√)

Now, x=√225

which will make it 15

as 15x15= 225

Hence 15 is the correct answer
