## how would you use Scientific notation

like take 9,000,000,000,000.0 and put in Scientific notation it would look something like these

9.0 x 10^12

9.0 x 10^12

## examples

10000 = 1 x 10424327 = 2.4327 x 104

1000 = 1 x 1037354 = 7.354 x 103

100 = 1 x 102482 = 4.82 x 102

10 = 1 x 10189 = 8.9 x 101

1 = 100

1/10 = 0.1 = 1 x 10**-**10.32 = 3.2 x 10**-**1

1/100 = 0.01 = 1 x 10**-**20.053 = 5.3 x 10**-**2

1/1000 = 0.001 = 1 x 10**-**30.0078 = 7.8 x 10**-**3

1/10000 = 0.0001 = 1 x 10**-**40.00044 = 4.4 x 10**-**4
