STANDARD FORM
Standard form is a way of writing very large numbers or
very small numbers in the form of A × 10n,
where 1≤A<10 and n is a positive or a negative
integer. Example 1:
Express each of the following numbers in standard
form.
(a) 7244
(b) 32567
(c) 750000
(d) 0.65
(e) 0.0428
(f) 0.000369
Solution:
(a) 7244 = 7.244 × 1000 =
7.244 × 103
(b) 32567 = 3.2567 × 10000 =
3.2567 × 104
(c) 750000 = 7.5 × 100000 =
7.5 × 105
(d) 0.65
=6.5×110
=
6.5 × 10-1
(e) 0.0428
=4.28×1100
=
4.28 × 10-2
(f) 0.000369
=3.69×110000
