Standard index form, also known as scientific notation, is commonly used by scientists, engineers, and mathematicians to simplify the representation of very large or very small numbers. It allows for easier calculations and clarity in communication, especially in fields such as physics, chemistry, and astronomy. Additionally, it is utilized in finance and data analysis to handle significant figures efficiently. This form is particularly useful in contexts where precision and scale are crucial.
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
uses of index
The number 3600 in standard index form is expressed as (3.6 \times 10^3). This representation indicates that 3.6 is multiplied by 10 raised to the power of 3, which equals 3600.
40.000000 in standard index form is 4.0 × 101
8890 in standard index form = 8.89 × 103
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
uses of index
4 x 10-1
The correct answer is 4.5 × 102
0.7 = 7.0 × 10-1
