What number is it when the the ones digit is one more than its tens digit and it's a composite number has two digits and it's even and has two less than a square number?
Let's list the requirements for the mystery number: One's digit more than the ten's digit. Composite number. Two digits. Even number. Is two less than a square. Now that we've listed the requirements, let's look for a place to "attack" the problem. The easiest is probably to look at squares since our mystery number is two less than a square. Here are the first few squares: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100 and 121. Since our mystery number is 2 less than a square, let's go through that. -1, 2, 7, 23, 34, 47, 62, 79, 98, 119. Now we'll look at two things at once; we'll look only at the 2-digit numbers that are even. (We don't have to look at the "composite number issue" because every even number except 2 is composite since it can be divided by 2.) 34, 62, and 98. Now the number with the one's digit greater than the ten's digit - and there's only one of them: 34. The number 34 has a one's digit greater than the ten's digit, is composite, has two digits, is even, and is 2 less than a square.
What is the digit in the tenths place is a prime number that is less than the digit 3 in the hundredths place?

Is 79 a composite number?

What is the only composite number less than 5?
4
Is 29 a two digit composite number?
no it is a prime number (prime means its multiples are only 1 and itself composite numbers can have multiples of many other things)
What is the largest 2 digit prime number?
97A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 97 is the largest 2 digit prime number.
How do you find if 1025 is composite number?
The only prime number that ends in 5 is 5.
The digit in the tenths place is a prime number that is less than the digit 3 in the hundredths place?
The only prime number less than 3 is 2.
What is the digit in the tenths place is a prime number that is less than the digit 3 in the hundredths place?
The only prime number less than 3 is 2.
Is 360 a prime or composite number?
A prime number is a number with two and only two factors: 1 (also known as unity) and itself. A composite number is a number with more than two factors; in other words, it has at least one factor besides 1 and itself. 360 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 5. (You can tell this because the last digit is a 0. If the last digit - the digit in the ones place - is a 5 or a 0, the number is divisible by 5.) Therefore, 360 is a composite number.
Is 1637143983 prime or composite?
1637143983 is not prime. Its prime factorisation is: 3 × 3 × 7321 × 24847.In the case of this number and one ninth of all integers, the fact that it is composite can be quickly determined by calculating the core digit value, the sum of all digits reduced to one digit. The core digit value of this number is 9, and every single integer with this core digit value is a multiple of 9. This can only prove that a number is composite. A core digit value other than 9 does not prove that a number is prime.
What is the smallest 1-digit composite number?
Referring to only positive integers, the smallest composite number is 4 (2 x 2). A composite number is any number that is the product of two or more prime numbers.*Referring to all integers, it would be the negative number -9, (3 x -3), which is the also the arithmetically lowest one-digit number. However, under normal definitions, negative numbers are not considered prime or composite numbers.
What are the factors of 5 in composite numbers?
5 is a prime number having 1 and 5 as its only factors. It makes no difference to the factors of 5 if the digit 5 is in composite numbers.
Is 55 composite or prime?
55 has factors other than 1 and itself, so it is not a prime number. For example, 55 is divisible by 5. (You can tell this because the last digit is a 5. If the last digit - the digit in the ones place - is a 5 or a 0, the number is divisible by 5.) Therefore, 55 is a composite number.composite
