✔ 最佳答案
1.用小數表示
4 x 10^(-8)
= 4 x 0.00000001
= 0.00000004
用分數表示
= 4 / 100000000
= 1 / 25000000
=====
2.
288365 x 10^(-7)
= 288365 x 0.0000001
= 0.0288365
288365 x 10^(-7)
= 288365 / 10000000
= 57673 / 2000000
=====
3.
用小數表示
13384 x 10^-8
= 13384 x 0.00000001
= 0.00013384
用分數表示
13384 x 10^-8
= 13384 / 100000000
= 1673 / 12500000
=====
4.
用小數表示
926644 x 10^(-7)
= 0.0926644
用分數表示
926644 x 10^(-7)
= 926644 / 10000000
= 231661 / 2500000

4乘10的-8
4*10^-8 = 0.00000004
288365乘10的-7
288365*10^-7 = 0.0288365
13384乘10的-8
13384*10^-8 = 0.00013384
926644乘10的-7
926644*10^-7 = 0.0922644
4*10^-8 = 0.00000004
288365乘10的-7
288365*10^-7 = 0.0288365
13384乘10的-8
13384*10^-8 = 0.00013384
926644乘10的-7
926644*10^-7 = 0.0922644
