A number produced by multiplying a number into itself, and that product again by the same number.

because it reapeats again the number 1

easy, just use this exmple! y=x2 plug in any real number for x then mulitply it again by the same number~. ;]

A rational number is defined as one that can be expressed as a ratio of two whole numbers, in other words, as a fraction. Again, by definition, an irrational number is one that CANNOT be expressed as a fraction.

Yes. Rational numbers repeat the SAME pattern over and over again; for example 0.343434... or 0.80122122122122... In the latter case, the period starts after some other digits; it is still rational.

If you sum all the digits in the number and, if the answer is greater than 9, repeat the process again and again, the final answer is 9.

No; the only condition for qualyfing as an irrational number is that the same pattern of digits doesn't repeat over and over again, as it does with a rational number. For example, 8/7 is a rational number; the decimal expansion is 1.142857 142857 142857 ... As you see, the same pattern of digits repeats over and over. The number may start with different digits, but if after a while the same pattern repeats again and again, the number is rational.The following number is irrational: 0.101001000100001000001 ... The pattern doesn't repeat, because a zero is added every time. And, in this example, the decimal expansion doesn't contain any digits other than 0 and 1.

There is no way to know how many significant digits are in 33000. If you are forced to choose then there are 2 significant digits but, again, there is really no way to tell. If the count of significant digits is important, the number should be expressed in scientific notation.

A repeated decimal is a decimal representation of a number in which, following a finite string of digits, the decimal digits settles into a string which repeats itself again and again - forever. For example, 111.11/77 = 1.44298701298701... The repeating pattern 298701 appears after the first three digits of the decimal representation.

Any number that repeats the same sequence of digits over and over again is rational. Note that it need not start with the repeated sequence of digits; the repetition may start after a certain point; such a number would also be rational, for example 0.88204204204204204...

an example of a physical change that can be reversed is like freezing water and letting melt back into water again

Infinitely many. The number pi , for example, is between 1 and 1000 and, since pi is a transcendental number, it contains infinitely many digits. Plus, there are all the irrational numbers - each with infinitely many digits, and all the rationals with recurring decimals - again with infinitely many digits.

The number before the decimal point is written in word form without suing "and". Next an "and is used where the decimal point appears. Then the number after the decimal point is written out in word form (again, without using "and"). Finally, the inverse power of ten is written and this is based on the number of digits after the decimal point.For 1 digit: tenths 2 digits: hundredths 3 digits: thousandths 4 digits: ten thousandths 5 digits: hundred thousandths 6 digits: millionths and so on.

Ther is at least one too many digits in your serial number. Please recheck and ask again

It means the same digit or group of digits keeps appearing again and again and again and . . . . .
