Use scientific counting method to express the following numbers: 1000 = 500000 = 35000 = 0.001 = 0.007 = 0.00056=

Use scientific counting method to express the following numbers: 1000 = 500000 = 35000 = 0.001 = 0.007 = 0.00056=

1000=1x10^3
500000= 5x10^5
35000=3.5x10^4
0.001=1x10^(-3)
0.007=7x10^(-3)
0.00056=5.6x10^(-4)
