limit as straight x rightwards arrow 0 to the power of plus of space straight f left parenthesis straight x right parenthesis equals straight b
limit as straight x rightwards arrow 0 of space open parentheses 1 plus ax close parentheses to the power of 1 over straight x end exponent equals straight b
limit as straight x rightwards arrow 0 of space open parentheses 1 plus ax close parentheses to the power of 1 over ax cross times straight a end exponent equals straight b
straight e to the power of straight a equals straight b
straight a equals log space straight b..... left parenthesis straight i right parenthesis
limit as straight x rightwards arrow 0 to the power of minus of space straight f left parenthesis straight x right parenthesis equals straight b

limit as straight x rightwards arrow 0 of space fraction numerator open parentheses straight x plus straight c close parentheses to the power of begin display style 1 third end style end exponent minus 1 over denominator open parentheses straight x plus straight c close parentheses to the power of 1 half end exponent minus 1 end fraction equals straight b
Put space straight x plus straight c equals straight h
straight x rightwards arrow 0 space then space straight h rightwards arrow straight c
limit as straight h rightwards arrow straight c of space fraction numerator straight h to the power of begin display style 1 third end style end exponent minus 1 over denominator straight h to the power of 1 half end exponent minus 1 end fraction equals straight b
limit as straight h rightwards arrow straight c of space fraction numerator begin display style fraction numerator straight h to the power of begin display style 1 third end style end exponent minus 1 over denominator straight h minus 1 end fraction end style over denominator begin display style fraction numerator straight h to the power of 1 half end exponent minus 1 over denominator straight h minus 1 end fraction end style end fraction equals straight b
fraction numerator begin display style 1 third end style over denominator begin display style 1 half end style end fraction equals straight b
2 over 3 equals straight b..... left parenthesis ii right parenthesis
