Question

Упростите выражение:20,004x-2,04x+2,045.Вычислите при x=101;1000;0,001.

Answer 1

20.004х-2.04х + 2.045 = 17.964х+2.045
если х=101, то 17.964х+ 2.045 = 17.964 • 101 + 2.045 = 1.814.364 + 2.045 = 1.816.409
если х=1000, то 17.964х+ 2.045 = 17.964 • 1000 + 2.045= 17.964000+2.045=20.009000 = 20.009
если х = 0.001, то 17.964х+ 2.045 = 17.964 • 0.001 + 2.045 = 0.017964 + 2.045 = 2.062964
