Answer 2

Answer:

All prime numbers between 20 and 35 are 23,29,31.

Step-by-step explanation:

Given,two numbers are 20 and 35.

Prime number is a number that is divisible only by 1 and itself.

For example, 3 is only divisible by 1 and 3.

So 3 is a prime number.All numbers between 20 and 35 are 21,22,23,24,25,26,27,28,29,30,31,32,33,34.

Here,21,22,24,25,26,27,28,30,32,33,34 all are divisible by some numbers other than 1 and itself.

So,21,22,24,25,26,27,28,30,32,33,34 are not prime numbers.

Therefore,23,29,31 are prime numbers between 20 and 35.

This is a problem of Algebra.

Some important Algebra formulas.

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab

(a + b)a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)
