Scientific Notation

0.000000084 in Scientific Notation = 8.4 x 10-8

7.3 x 106

Because it uses fewer digits as for example 9,000,000,000,000,000 in scientific notation is 9.0*10^15

0.0000156 = 1.56 x 10^-5

2.5E-2 is the scientific notation.

Technically it is 2.5x10-2 , E is calculator notation and would not be officially acceptable, for example, on a test.

3.3e+12 = 3 x 10^12 = 3,300,000,000,000 = 3.3 trillion

186,000 = 1.86e+5

40100000000000 in scientific notation is: 4.01*10^13

It is: 2.34*10^4 s

Add the exponents and multiply the decimals as for example:-

2.5*10^4 times 3.75*10^3 = 9.375*10^7

It is: 6.0*10-4

11.5 = 1.15 * 10^1

8.2 times 10 to the 2nd power

Best illustrated with examples (scientific notation on the right):

1) 24578 = 2.4578x104

2) 0.00000345 = 3.45x10-6

3) 2.313 = 2.313x100

4) -49 = -4.9x101

and so on.

=============================

4.38904 times 105.

It is 3.06*10^5

2.453 x 10^2

It is: 10,000,000,000,000 times 100,000,000,000 = 1.0*10^24 expressed in scientific notation

It is: 3.8*10^-3

1.86 x 10^5 miles/sec

4 x 101.

223 = 2.23 × 102

It is: 2.3*10-7

3.6 x 10^1

300000 in scientific notation is: 3 × 105
