Scientific Notation

Interpret the number as 76000.0. Then, shift 4 decimal places to the left, so the exponent for base 10 is 4. Therefore, we obtain:

7.6 x 104.

5,806 in Scientific Notation = 5.806 x 103

9,040, in scientific notation, can be 9.04x103.

1.3 x 10^4

It is: 1.3*10^4

5.3x101

It is 2.24*10^-4 in scientific notation

4.7 x 10 ^ -9

6.83 × 10-4

or

6.83E-4

22,000 = 2.2 × 104

7.0043*109

0.010 in Scientific Notation = 1.0 x 10-2, since they specified the rightmost 0, it is considered significant.

This number in scientific notation is 9.8x10-5.

4.5 X 10^5

100 billion in scientific notation is: 1.000000e+11

2.16*10

To write repeated multiplication in an exponential notation, you should write the number that has to be multiplied as the base. Count the number of times that the number is used.

25,000,000 = 2.5 x 107

Scientific notation is a way of writing numbers that are too big or too small to be conveniently written in decimal form.

In normalized scientific notation all numbers are written in the form a x 10^b (a times ten raised to the power of b) where a is a nonzero single-digit integer and b is an integer.

953 in scientific notation is 9.53 x 10^2

7.5 x 10^-3

Biologists would use scientific notation is studying micro-organisms. Even with macro-organisms, there are cellular characteristics which can only be studied using very small numbers. On the other hand, the study of DNA requires very large numbers.

589,000 in Scientific Notation = 5.89 x 105

9.321*10

8,394,000,000 = 8.394 × 109
