Question

Kindly help me in this maths question

Answer 1

Step-by-step explanation:

a^m/a^n = a^(m-n)

(a^(m-n))^(m+n) = a^(m-n)(m+n) = a^(m²-n²) ---1

a^n /a^l = a^(n-l)

(a^n/a^l)^(n+l) = a^(n-l)(n+l) =a^(n²-l²) ---2

a^l/a^m = a^(l-m)

(a^l/a^m)^(l+m) = a^(l-m)(l+m) = a^(l²-m²) ---3

1×2×3

a^(m²-n²+n²-l²+l²-m²) = a⁰ =1
