Question

how to find power notation easily​

Answer 1

Answer:

scientific notation is a standard way of writing very large and very small numbers so that they are easier to both compare and use it in computations.

Step-by-step explanation:

For example,

To see an exponent that's positive,write 312,000,000,000 in scientific notation:

1. Move the decimal place to the left to create a new number from 1 upto 10

So,N=3.12.

2. Determine the exponent, which is the number of times you moved the decimal

10^11 (10to the power 11)

3. Put the number in the correct form for scientific notation

(N*10a)

=312,000,000,000=3.12*10^11

To see an exponent,that's negative .00000031 in scientific notation:

1. Move the decimal place to the right to create a new number from 1 upto 10

So,N=3.1

2. Determine the exponent,which is the number of times you moved the decimal

10^-7

3. Put the number in the correct form for scientific notation

N*10^a

=.00000031=3.1*10^-7

Hope this answer helped you......!

Answer 2

Scientific Notation (also called Standard Form in Britain) is a special way of writing numbers:

Like this: scientific notation 700 = 7x10^2

Or this: scientific notation 4,900,000,000 = 4.9x10^9

It makes it easy to use big and small values.
