Answer 1

Answer:

If n is a rational number, then 5^2n-2^2n is divisible by 0

Answer 2

The number is divisible by both 7 and 3

Step-by-step explanation:

If n is a rational number

then

$5^2^n - 3^2^n$ is in the form of $a^2^n - b^2^n$

which is divisible by both

(a+b) and (a-b)

so, here , a = 5  and b = 3

therefore ,

$5^2^n - 3^2^n$ is divisible by both 7 and 3

hence ,The number is divisible by both 7 and 3
