Question

write factors using prime factorization method : 215​

Answer 1

Answer:

215 and Level 3

215 is a composite number.

Prime factorization: 215 = 5 x 43.

The exponents in the prime factorization are 1 and 1. ...

Factors of 215: 1, 5, 43, 215.

Factor pairs: 215 = 1 x 215 or 5 x 43.

Since 215 has no square factors, the square root of 215 cannot be simplified.

Answer 2

Step-by-step explanation:

215 is a composite number.

Prime factorization: 215 = 5 x 43

The exponents in the prime factorization are 1 and 1. Adding one to each and multiplying we get (1 + 1) x (1 + 1) = 2 x 2 = 4. Therefore 215 has 4 factors.

Factors of 215: 1, 5, 43, 215

Factor pairs: 215 = 1 x 215 or 5 x 43

Since 215 has no square factors, the square root of 215 cannot be simplified. √215 ≈ 14.663
