How do write a number example 120 as a product of their prime factors and give answers in index notation?
23 x 3 x 5 = 120
If you prime factorize a number and you use the ladder method why do you always have to divide by prime numbers?
It's more efficient. You want to end up with all prime numbers. You could divide by a composite number, but you'd just have to break that number down later. It saves steps.
Is 4181 a prime number?
No. For example: 4181 / 37 = 113 so it can't be prime. But 4181 is the first composite number in the Fibonacci sequence with a prime index. ;)
Why prime and composite numbers help with math?
You can use prime numbers to factorize numbers, a very useful tool
What is the prime number using exponential notation 72?
23 x 32
What is the prime number using index notation of 243?
35 = 243
What is the factor of 54 index notation?
2 x 33 = 54
What is 25 as a product of its prime factors using index notation?
5^2
How do write a number for example 120 as a product of its prime factors and give answers in index notation?
As a product of its prime factors: 23*3*5 = 120
What is the index notation of 294?
The index notation of 294 is 2 x 3^5, where 2 is the base and 5 is the exponent. This means that 294 can be expressed as the product of 2 and 3 raised to the power of 5. In index notation, the number is broken down into its prime factors and expressed as a product of primes with corresponding exponents.
What are the factors and prime factors of 22 and it index notation?
1, 2, 11, 22 2 and 11 are prime.
How do write a number example 120 as a product of their prime factors and give answers in index notation?
23 x 3 x 5 = 120
Express 1936 as a product of prime factors in index notation?
It is: 24*112 = 1936
How do you write 48 as a product of its prime factors in index notation?
48 = 24 x 3
How do you use index notation to write 15 as a product of its prime factors?
15 = 31*51
How do you factorize 10?
break it into prime number multiples,10 = 2 * 5 (both prime numbers)example: factorize 387(387) = 9 * 43 (both primes , end of excercise)factorize 390:(390) = 2 * (195) = 3 * (65) = 5 * 13 (both primes , end of excercise)
What can you learn about prime and composite number while playing the factor game?
If you play the factor game, you factorize the number. If the number of factors are only 2 including 1 and number itself, then it is a prime.
