Question

Which number is not in scientific notation?

1.1 ⋅ 10213
7.8 ⋅ 108
3.02 ⋅ 10−10
35 ⋅ 104

Answer 1

35*10^4 as with scientific notation, you must have just 1 number before the decimal point

Answer 2

35 .10¨4 ---> is not in scientific notation

Step-by-step explanation:

The scientific notation is used to express very long numbers in a short way. For that, it is necessary that the entire number be represented by a number from 1 to 9 (just single digit numbers), and of course it can be followed by decimals. Then this number is multiplied by a power of 10.

To conclude, the correct way to represent that number should be:

3,5 . 10∧5

10 must be potentiated by 5 because there is one more decimal number.
