Question

A number m is formed by writing all the prime numbers between 0 and 10 in ascending order. another number n is formed by writing all the square numbers between 0 and 10 in descending order: a)find m -n b)express(m-n) as a product of its prime factors

Answer 1

Answer:

(a) 1416

(b) 2 × 2 × 2 × 3 × 59

Step-by-step explanation:

The prime numbers between 0 and 10 are 2, 3, 5,7 (1 is not considered prime)
Therefore m = 2357

The square numbers between 0 and 10 are  1, 4, 9 and in descending order 9,4.1so n = 941

m - n = 2357 - 941 = 1416

Unique prime factors of 1416 are 2,3,59

1416 as a product of prime factors = 2 × 2 × 2 × 3 × 59
