ABSTRACT
Assuming all quantities are real, a > 0, b > 0, and no denominators are zero: https://www.w3.org/1998/Math/MathML"> a x a y = a x + y , a x a y = a x - y , ( a b ) x = a x b x , $$ a^{x} a^{y} = a^{{x + y}} ,~\frac{{a^{x} }}{{a^{y} }} = a^{{x - y}} ,~(ab)^{x} = a^{x} b^{x} , $$ https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315154978/d4fadf3f-0d14-435f-8ef5-075606867872/content/math2_1.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/>
