No because its prime factorization is: 2*3*7 = 42
The prime factorization of 42 does not use exponents: 2 x 3 x 7
The prime factorisation of 42 is 2*3*7.
The prime factors of 42 are 2, 3 and 7.
No because as a product of its prime factors: 2*3*7 = 42
No because its prime factorization is: 2*3*7 = 42
No. Prime factorization is the method of expressing a number as the product of prime numbers. So, Prime factorization of 42 = 2x3x7
You find the prime factorization of 42 like this. You think what 2 number multiplied together give you 42: 6x7 7 is prime because the only factors it has is 1 and itself. 6 can be broken into 3x2. So you currently have 7x3x2. All these numbers are prime so you just found the prime factorization!
In actual fact, the prime factorization of 42 is not 21 x 2, as 21 is not a prime number. The complete prime factorization of 42 is 2 x 3 x 7.
No, 21 is not prime.
No.
42=2x21 21=3x7 PF=2x3x7 The PF (Prime Factorization) of 42 is 2x3x7.(Sorry, I couldn't do a factor tree, there are always helpful to use when doing prime factorization, but since this is the computer, I could only do it like the following above.)
The prime factorization of 42 does not use exponents: 2 x 3 x 7
It is: 2*3*7 = 42
No.
