Scientific Notation

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

186,000 = 1.86e+5

It is: 2.34*10^4 s

40100000000000 in scientific notation is: 4.01*10^13

11.5 = 1.15 * 10^1

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

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

8.2 times 10 to the 2nd power

It is: 6.0*10-4

4.38904 times 105.

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.

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

It is 3.06*10^5

1.86 x 10^5 miles/sec

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

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

Oh, dude, scientific notation is like when you take a number and write it as a number between 1 and 10 multiplied by a power of 10. So, for 112, you'd write it as 1.12 x 10^2. It's like shorthand for big numbers, you know?

1.488 × 108

or

1.488E8

9.27*106
