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
