What is gcd of numbers like (n^13-n)?

GCD(=n

Step-by-step explanation:

We are given that two numbers and n

We have to find the gcd of two given numbers

GCD: It is also called HCF. It is defined as the highest common facotors of two  more numbers.

To find the gcd of two given numbers first we find the factor of two numbers then we find highest common factors .

( 13 times )

Factors of are 1,n,n,n....n(13 times)

Factors of n are 1,n

Common factors of two given numbers are 1 ,n

Highest common factor of two given numbers  is n.

Therefore, gcd of two given numbers is n.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
