(0.1)^-2=100
(1+0.1)+(2+0.1*2)+(3+0.1*3)+...+(99+0.1*99)+(100+0.1*100)等于几
(-0.1)乘以(-100)乘以(-0.01)=?
百分数化分数 1%= 125%= 65%= 10%= 95%= 0.1%= 4%= 100%= 40%= 14%= 2%
请详细讲讲这题100(0.1X-0.2)/2-10(X+1)/5=3 500(0.1X-0.2)-20(X+1)=30
如果规定:0.1=1/10=10的-1次方,0.01=1/100=10^-2,0.001=1/1000=10^-3,
规定:0.1=1/10=10^-1,0.01=1/100=10^-2,0.001=1/1000=10^-3
如果规定:0.1=10分之一=10的-1次方,0.01=100分之一=10的-2次方,0.001=1000分之一=10的
如果规定:0.1=1/10=10的-1次方,0.01=1/100=10^-2,0.001=1/1000=10^-3,..
1元=100分 1元 0.1元×0.1元=0.01元 0.0
分别指出,当x取何值时,下列各等式成立 (1)1/32=2^x (2)10^x=0.01 (3)0.1^x=100
(0.3-X)*(X/0.1*100+500)=120
3[100-x]=1500*0.1,怎么解
