Is 45 a Perfect Square?
A perfect square is a number obtained by multiplying an integer (or a whole number) by itself. Whole numbers consist of the positive integers including 0, 1, 2, 3, 4, 7, 8, and 9. Whole numbers do not include numbers like -5, 7.025, or 5 ½. For example, 81 is a perfect square since it can be expressed as the product of 9 multiplied by itself, where 9 is an integer (or whole number).
In our example the square root of 45 is approximately 6.708204. Since 6.708204 is not a whole number, therefore 45 is not a perfect square.
ANSWER: 45 is not a perfect square.
In our example the square root of 45 is approximately 6.708204. Since 6.708204 is not a whole number, therefore 45 is not a perfect square.
ANSWER: 45 is not a perfect square.
Is the square root of 45 rational or irrational number?
A number is considered a rational number when it can be divided by a whole number and the result is also a whole number. In other words, a rational number is a quotient of two integers. An integer is a number that does not contain a fractional part and can be either positive, negative, or zero. In simpler terms, a number is considered rational if it can be expressed as a ratio of two integers.
One can determine whether 45 is a perfect square quickly by considering that all perfect squares have rational square roots, while the square roots of non-perfect square numbers are irrational. Given that 45 is not a perfect square, it follows that the square root of 45 is an irrational number.
ANSWER: The square root of 45 is an irrational number.

ANSWER: The square root of 45 is an irrational number.
Principal square root of 45
Each positive number has a pair of square roots, comprising one positive and one negative. For instance, for the number 45, the square roots are -6.708204 (negative) and +6.708204 (positive), as both (-6.708204)^2 and (+6.708204)^2 give 45. The positive square root is known as the "principal square root." Generally, when we calculate "the square root of a number," we refer to the principal square root. For the square root of 45, the principal square root is the positive value, represented as √45 = 6.708204.
