总述:本次共解1题。其中
☆算术计算1题
〖1/1算式〗
作业:求算式 -3/5*log(2,3/5)-2/5*log(2,2/5) 的值.
题型:数学计算
解:
-3/5*log(2,3/5)-2/5*log(2,2/5)
=-3/5*(-0.736966)-2/5*log(2,2/5)
=-3/5*(-0.736966)-2/5*(-1.321928)
=-0.6*(-0.736966)-2/5*(-1.321928)
=0.44218-2/5*(-1.321928)
=0.44218-0.4*(-1.321928)
=0.44218-(-0.528771)
=0.970951 答案:-3/5*log(2,3/5)-2/5*log(2,2/5)=0.970951你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
