Answer 1

Answer:

Step-by-step explanation:

If any same variable(a) is given at numerator as well as in denominator with different powers(m,n) then the resultant form is a^(m - n)

So, given question is written as

(a)^(m-n)(m+n) x (a)^(n-l)(n+l) x (a)^(l-m)(l+m)

(a)^(m^2-n^2) x (a)^(n^2- l^2) x (a)^(l^2-m^2)

And if same variable has in multiple form with different powers then powers will add.

(a)^(m^2 - n^2 +n^2 - l^2 +l^2 - m^2)

(a)^(0)
