考點(diǎn):負(fù)整數(shù)指數(shù)冪,同底數(shù)冪的乘法,冪的乘方與積的乘方,零指數(shù)冪
專題:
分析:根據(jù)同底數(shù)冪相乘,底數(shù)不變指數(shù)相加;
根據(jù)任何非零數(shù)的零指數(shù)次冪等于1,負(fù)整數(shù)指數(shù)次冪等于正整數(shù)指數(shù)次冪的倒數(shù)進(jìn)行計(jì)算即可得解;
把42014寫成4×42013,然后根據(jù)積的乘方的性質(zhì)進(jìn)行計(jì)算即可得解.
解答:解:2

2014,
=(-0.25)
2013×4×4
2013,
=(-0.25×4)
2013×4,
=-1×4,
=-4.
故答案為:-32,
,-4.
點(diǎn)評(píng):本題考查了負(fù)整數(shù)指數(shù)次冪等于正整數(shù)指數(shù)次冪的倒數(shù)的性質(zhì),零指數(shù)冪的定義,是基礎(chǔ)題,熟記概念與性質(zhì)是解題的關(guān)鍵.
