which are natural numbers TT -sqrt4 , 9/8 , sqrt1

3 answers

To determine which of the given expressions are natural numbers, let's evaluate each one individually:

  1. \( TT - \sqrt{4} \)

    • \( \sqrt{4} = 2 \)
    • Without a value for \( TT \), we can't determine whether this is a natural number.

  2. \( \frac{9}{8} \)

    • This evaluates to 1.125, which is not a natural number.

  3. \( \sqrt{1} \)

    • \( \sqrt{1} = 1 \), which is a natural number.

In conclusion, based on the information provided, the only natural number is \( \sqrt{1} = 1 \). We cannot determine the natural number status of \( TT - \sqrt{4} \) without more information about \( TT \).

is 6/10 a natural number

No, \( \frac{6}{10} \) simplifies to \( \frac{3}{5} \), which is not a natural number. Natural numbers are positive integers (1, 2, 3, ...) and do not include fractions or decimals. Therefore, \( \frac{6}{10} \) is not a natural number.
