2. 不计算,运用规律直接写出得数。(10☆)
(1)$ 0.1 + 0×0.9 = 0.1 $
(2)$ 99×99 = 9801 $
$ 0.2 + 1×0.9 = 1.1 $
$ 999×999 = 998001 $
$ 0.3 + 12×0.9 = 11.1 $
$ 9999×9999 = 99980001 $
$ 0.4 + 123×0.9 = ($
111.1
)
$ 99999×99999 = ($
9999800001
)
$ 0.5 + 1234×0.9 = ($
1111.1
)
$ 999999×999999 = ($
999998000001
)

答案

(1) 111.1 1111.1
(2) 9999800001 999998000001
