4. WHY DO WE USE
METRIC PREFIXES
For Example If we are given a
number such that:
25000000000000 bytes.
Sometime we may not be
able to count the number of
zeros, so here prefixes are
used for easiness.
See Example (i)
USES EXAMPLE
Example(i):
25000000000000 bytes can be
written as:
25TB(Tera Bytes)
Example(ii):
0.000001 seconds can be
written as 1Us (Micro Seconds)
7. MEHTODOLOGY
In order to write a number
into the scientific Notation we
have to shift the decimal
point either on the right or left.
In case of right shifting of
decimal point the power on
the base will be negative i.e
0.00004 can be written in
Scientific notation as
4x10^-5
In case of left shifting of
decimal point the power on
the base will be positive i.e
1000 can be written in
Scientific notation as
1x10^3
