Yes; the square root of 225 is both a positive and a negative 15. Therefore, the square root of 225 is an integer.
15 and -15
Technically, every positive number is a square in the real number system, but I assume you mean perfect square. And yes, 225 is a perfect square. 152 = 225
Because some of them are squares of rational numbers. So their square roots are the rational numbers.Thus if x is rational, then the square roots of x2, which are -x and +x are both rational.
The discriminant of the equation ... (b2-4ac) = (225-160) ... is real and positive, so the roots are real and unequal.
Yes; the square root of 225 is both a positive and a negative 15. Therefore, the square root of 225 is an integer.
The square roots of 225 are +15 and -15 .
15. 15*15 = 225
The principal (positive) square root of 225 is 15.
They are 15 and -15
15 and -15
It is 15, -15.
The square root of 100 = 10 The square root of 225 = 15 The sum = 10 + 15 = 25
Technically, every positive number is a square in the real number system, but I assume you mean perfect square. And yes, 225 is a perfect square. 152 = 225
