☆算术计算1题
〖1/1算式〗
作业:求算式 (0.15-0.05)×0.0064+(0.1-0.05)×0.01-(0.15+0.1-2×0.05)×0.5×0.1×0.08 的值.
题型:数学计算
解:
(0.15-0.05)×0.0064+(0.1-0.05)×0.01-(0.15+0.1-2×0.05)×0.5×0.1×0.08
=0.1×0.0064+(0.1-0.05)×0.01-(0.15+0.1-2×0.05)×0.5×0.1×0.08
=0.1×0.0064+0.05×0.01-(0.15+0.1-2×0.05)×0.5×0.1×0.08
=0.1×0.0064+0.05×0.01-0.15×0.5×0.1×0.08
=0.00064+0.05×0.01-0.15×0.5×0.1×0.08
=0.00064+0.0005-0.15×0.5×0.1×0.08
=0.00064+0.0005-0.075×0.1×0.08
=0.00064+0.0005-0.0075×0.08
=0.00064+0.0005-0.0006
=0.00114-0.0006
=0.00054 答案:(0.15-0.05)×0.0064+(0.1-0.05)×0.01-(0.15+0.1-2×0.05)×0.5×0.1×0.08=0.00054你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
