Sixth law If `a b` are non-zero rational numbers and n is a positive integer then `(a/b)^-n = (b/a)^n`

Fifth law If ab are non-zero rational numbers and n is an integer then ((a)/(b))^(n)=(a^(n))/(b^(n))

Fourth law If ab are non-zero rational numbers and n is integer then (ab)^(n)=a^(n)b^(n)

First law If a is a non-zero rational number and mn are integers then a^(m)a^(n)=a^(m+n)

If a and b are non-zero rational numbers and n is a natural number then (a^(n))/(b^(n))=((a)/(b))^(n)

Fourth law if ab are non -zero rational numbers and n is a natural number then *a^(^^)n=(ab)^(^^)n

Second law If a is a non-zero rational number and mn are integers then a^(m)-:a^(n)=a^(m-n) or (a^(m))/(a^(n))=a^(m-n)

Third law If a is a non-zero rational number and mn are integers then (a^(m))^(n)=a^(mn)=(a^(n))^(m)

First law if is any non -zero rational number andmn are natural numbers then a^(m)xx a^(n)=a^(m)+n

x^(m)xx x^(n)=x^(m+n) , where x is a non zero rational number and m,n are positive integers.

If n is an odd positive integer, then a^(n)+b^(n) is divisible by
