Answer 1

分析：本題涉及零指數(shù)冪、負(fù)整數(shù)指數(shù)冪、絕對(duì)值、有理數(shù)的乘方等知識(shí)．在計(jì)算時(shí)，需要針對(duì)每個(gè)考點(diǎn)分別進(jìn)行計(jì)算，然后根據(jù)實(shí)數(shù)的運(yùn)算法則求得計(jì)算結(jié)果．

解答：解：原式=27+4-1+1=31．故答案為31．

點(diǎn)評(píng)：本題考查實(shí)數(shù)的運(yùn)算能力，解決此類題目的關(guān)鍵是熟練掌握負(fù)整數(shù)指數(shù)冪、零指數(shù)冪、乘方、絕對(duì)值等考點(diǎn)的運(yùn)算．注意：負(fù)指數(shù)為正指數(shù)的倒數(shù)；任何非0數(shù)的0次冪等于1；絕對(duì)值的化簡．
