Is 7.1234 is a rational number?
Yes.
Is 8.2 a rational number?
Yes. Any terminating decimal is a rational number. Any repeating decimal also.
What is an imperfect square?
Basically a perfect square is a number like 81 or 100. When these numbers are square rooted, they equal whole numbers like 9 or 10. An imperfect square is a number that when is square rooted equals and repeating decimal, like 29 when square rooted equals 5.385164807134504... (Note: Both even and odd number can be imperfect or perfect squares.)
How do you check if a number is a perfect square?
For a number to be a perfect square, the number's square root has to be a whole number. 9 is a perfect square because its square root is a whole number, 3. If the square root of the number is a decimal, then it is not a perfect square. For example, 13 does not divide evenly so it not a perfect square.
What is the perfect square whole number closest to 54362?
Rounded to two decimal places, sqrt(54362) = ±233.16
Is the square root of 257 an irrational number rational number o an whole number?
The square root of 257 is an irrational number, as it cannot be expressed as a fraction or whole number. It is a non-repeating, non-terminating decimal.
How can a decimal greater than 1 be a repeating decimal?
A decimal number is like a mixed fraction: it has an integer part and a fractional part. If the fractional part is a repeating fraction then the whole number is represented by a repeating decimal.
Is 7.1234 is a rational number?
Yes.
Is 8.2 a rational number?
Yes. Any terminating decimal is a rational number. Any repeating decimal also.
Is a decimal that ends with . terminating or repeating?
If it ends in a decimal, then it must be a whole number. Repeating could be ruled out immediately because even though theoretically it could be a thought of as a repeating decimal with infinite zeros repeating, adding zeros doesn't change the quantity and you could in theory add infinite zeros to the end of ANY decimal. That does not make it repeating.
Is the square root of 2 a whole number?
No, it's a decimal number. 1,4142135623730950488016887242097
Why does 39 divided by 99 equal 0.39393939 repeating?
Simply because the solution to your sum produces a repeating decimal. Just as 22/7 (The value of Pi as a fraction) produces the repeating decimal 3.142857

Does a square root need to be a whole number?
No, it does not; it could be a fraction (or, what amounts to the same thing, a repeating decimal), a negative number (in fact every strictly positive number has 2 square roots, one positive, one negative, such as the square roots of 25 are 5 and -5), an irrational number (like the square root of 2), or an imaginary number (like the square root of -49).
Is the number 2002 square?
The number 2002 is not square. For a number to be square, its square root must be a whole number (nothing to the right of the decimal). The square root of 2002 is 44.74371464...
Is the square root of 12 a natural number?
No. A natural number is a whole number, that is, no digits after the decimal point. Calculate the square root of 12 on a calculator, and you will see that it is not a whole number.
Can an irrational number ever be a natural number a whole number?
Irrational numbers have infinitely long, non-repeating decimal expansions. They cannot be natural numbers or whole numbers. Those are rational.
