Index notation rules
WebOnce index notation is introduced the index laws arise naturally when simplifying numerical and algebraic expressions. Thus the simplificiation 2 5 × 2 3 = 2 8 quickly leads to the rule a m × a n = a m + n, for all positive integers m and n. As often happens in mathematics, it is natural to ask questions such as: http://amsi.org.au/teacher_modules/Indices_and_logarithms.html
