Standard index form is a convenient way to represent very large or very small numbers. It is often used in physics where these extreme values are used regularly.
E.g.
6.63 x 10-34 is a common value used.
5 x 102 is 500
which is equivalent to 5 x 10 x 10
5 x 10-2 is 0.05
which is equivalent to 5 / 10 / 10
8890 in standard index form = 8.89 × 103
450 in standard index form = 4.5 × 102
40.000000 in standard index form is 4.0 × 101
No. In the index form a number is expressed as a multiple of its prime factors whereas in the standard form it is expressed as a number between in the range [1, 10) multiplied by an integer power of 10. So, for example, 1728 in index form = 26*33 1728 in standard form = 1.728*103 The index form can only be used for integers.
4 x 10-1
8890 in standard index form = 8.89 × 103
450 in standard index form = 4.5 × 102
40.000000 in standard index form is 4.0 × 101
5,200 in standard index form = 5.2 × 103
2.9 million in standard index form = 2.9 × 106
1250 in standard index form = 1.25 × 103
No. In the index form a number is expressed as a multiple of its prime factors whereas in the standard form it is expressed as a number between in the range [1, 10) multiplied by an integer power of 10. So, for example, 1728 in index form = 26*33 1728 in standard form = 1.728*103 The index form can only be used for integers.
2 × 10^-7 is in standard [index] form. In normal form it is 0.0000002
1.203*10-8
4 x 10-1
0.7 = 7.0 × 10-1
The correct answer is 4.5 × 102
