Question

Express the following as the sum of twin primes (1) 60 (2) 144
(3) 84 (4) 120

Answer 1

Answer:

Step-by-step explanation:

Our aim is to express the following as the sum of twin primes (1) 60 (2) 144  

(3) 84 (4) 120.

Firstly lets define twin prime numbers.

Two twin prime numbers are numbers which are primes and the difference between them is equal to 2.

Hence, one way of solving this is:

a) lets start by dividing 60 by 2, and get 30, then lets add 1 and subtract 1 to 30, and sum them:

29 + 31 = 60

And this process can be done to all of them. Please check if they are always prime ;)

b)

144/2 = 72

71 + 73 = 144

c)

84 / 2 = 42

41 + 43 = 84

d)

120 / 2 = 60

61 + 59 = 120

Hence, we reached our aim.

I hope this helps you!

Good studies!!
