Here, is your answer (x^m/x^n)^l * (x^n/x^l)^m * (x^l/x^m)^n =(x^ml/x^nl)*(x^nm/x^lm)*(x^ln/x^mn) =(x^ml-nl)*(x^nm-lm)*(x^ln-mn) =x^[(ml-nl)+(nm-lm)+(ln-mn)] =x^ml-nl+nm-lm+ln-mn Therefore, same variables with negetive and positive signs are cancelled (example:- ml and -ml are cancelled) = x Hope it helps you

Heron's formula named after Hero of Alexandria, gives the area of a triangle when the length of all three sides are known. Unlike other triangle area formulae, there is no need to calculate angles or other distances in the triangle first.
