分析:(1)先去括號(hào),再把所得的結(jié)果合并即可;
(2)利用乘法的分配律分別進(jìn)行計(jì)算即可;
(3)先把除法轉(zhuǎn)化成乘法,再按有理數(shù)的混合運(yùn)算順序進(jìn)行計(jì)算即可;
(4)先算乘方,再把除法轉(zhuǎn)化成乘法,最后約分即可;
(5)先算乘方,再算乘法,最后把所得的結(jié)果合并即可;
(6)先去小括號(hào),再算乘方,再算乘法,最后把所得的結(jié)果合并即可.
點(diǎn)評(píng):此題考查了有理數(shù)的混合運(yùn)算,解題的關(guān)鍵是掌握有理數(shù)混合運(yùn)算的順序和法則,在計(jì)算時(shí)注意簡(jiǎn)便方法的運(yùn)用和結(jié)果的符號(hào).
