0.25²-8的⅔次方-(1/16)的0.75次方-2log5的10次方-log5的0.25次方
问题描述:
0.25²-8的⅔次方-(1/16)的0.75次方-2log5的10次方-log5的0.25次方
答
0.25²=1/16
0.25²-8的⅔次方-(1/16)的0.75次方-2log5的10次方-log5的0.25次方
=1/16-(2^3)^(2/3)-(1/16)的3/4次方-log5的100次方-log5的0.25次方
=1/16-4-1/8-(log5的100次方+log5的0.25次方)
=1/16-4-1/8-log5的25
=1/16-4-1/8-2
=-6又16分之一
答
0.25²-8⅔次方-(1/16)的0.75次方-2log(5)10-log(5)0.25
=0.0625-4-0.125-log(5)[100*0.25]
=-4.062-2
=-6.062
答
0.25²-8的⅔次方-(1/16)的0.75次方-2log5的10次方-log5的0.25次方
=1/16-4-1/8-log5 10^2-log5 0.25
=-4-1/16-log5 100*0.25
=-4-1/16-2
=-97/16
