Can you factorise every palindrome with odd number of digits?
No. 101 is prime.
What are the kinds of decimal?
There are three main types of decimal numbers:Terminating: these come to an end after a finite number of digits. These are the number 0 and also numbers such that their rational representation in the simplest form has a denominator whose only prime factors are 2 and 5.Repeating: these have a string of digits which repeats without end. The string may start afetr a finite number of non-repeating digits. For example, 2.1346515235235235... has the 3-digit string "235" repeating, but not straight away. These are numbers whose rational representation in the simplest form has a denominator which has a prime factor other than 2 or 5.Non-terminating and non-repeating: these have an endless number of digits with no repeating strings. These digits may be random or may contain patterns, such as 5.12122122212222.... but there cannot be a repeating string. These are irrational numbers.
How many prime numbers can be made with the digits 1 to 9 without repeating a digit?
first A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself so 1 isnt a prime primes are 2 3 5 7 11 13 17 etc now by repeating digits if you mean the 1's in 11 then stop at 7 if you mean repeating a digit as in the tens spot of 11 and 13 stop at 11 and 3 and 13 are repating the 3 location....etc
What an Operation to change a ratio to a decimal?
It is dividing the dividend by the divisor untilthere is no remainder; orthe digits in the quotient start repeating; oryou have reached a satisfactory degree of accuracy.The last bullet is because some fractions will not start repeating for a long time. Most primes will take as many digits as the prime itself: for example, 1/29 has a repeating string which is 29-digits long.
Maths. what is to factorise?
To factorise is to find the numbers that divide into the original number by only using prime numbers. For example factorise 20 = 2 times 2 times 5
How do you know if a decimal is terminating or repeating?
If you know what rational fraction it represents then, if the denominator in the fraction's simplest form has any prime factor other than 2 and 5, then it is a repeating decimal and if not it is terminating.Otherwise you need to examine the digits of the decimal representation in detail. Remember though, that the repeating string could be thousands of digits long (or even longer).
How can you tell if a rational number is repeating without dividing?
If the denominator has ANY prime factor other than 2 or 5, then the decimal is repeating.
If a denominator is a prime number is the decimal repeating?
No. 2 is a prime but 1/2 is not a repeating decimal.
What is a prime number with identical digits?
A prime number with identical digits is 11.
How many prime digits between 1and 50?

A prime number with two identical digits?
The number 11 is prime and has two identical digits.
What is the smallest two-digits prime number whose digits are also prime themselves?
