Scientific Notation

4 and 8 thousandths (4.008) in standard form is 4.008 × 100

9.9 × 103

3.6084 × 107

74,977 = 7.4977e4 or 7.4977 x 10^4

9.6 x 10^-2

It is 9.5*10^-4 in scientific notation

605,000,000 in Scientific Notation = 6.05 x 108

A large number like this would be rounded to 30,000,000,000 and then expressed in scientific notation as: 3.0*1010

1.3 × 10-18

or

1.3E-18

0.0000179 = 1.79 × 10-5

700 ten thousandths in scientific notation is: 7e-2 or 7 x 10^-2

It is 1.79875475*107, although it would make sense to reduce the number of figures in the mantissa: for example to 1.80*107.

0.00000142 = 1.42e-6

7.86 x 10^5

It is: 1.2*10^13

It is: 1.21*10^-2

0.02 = 2 x 10^-2

1,550 = 1.55 x 10^3

0.000421 in scientific notation is 4.21x10-4

It is 3.7*10^-2

5.3 x 10^-4

It is: 2.4*10^5 in scientific notation
