Question

Express in scientific notation. Remember, M must be a number 1 ≤ M < 10. 0.00000000000013 =

Answer 1

counting the number of zeros + 1 we get 13

so its 1.3 * 10^-13

Answer 2

The scientific notation is:

`0.00000000000013=1.3* 10^(-13)`

Explanation:

We know that the scientific notation of a decimal number is such that the number is given in the form of:

1) There should be one non-zero digit before the decimal.

2) The number of shifting of the decimal will be counted as the power of 10.

i.e. if the decimal is shifted n units to the left then the power of 10 will be actual power+n and if the decimal is shifted to the right then the number of shifts will get subtracted to the actual power of 10.

Here the number is:

0.00000000000013

Here we shift the decimal 13 places to the right.

Hence, the number in scientific notation is:

`1.3* 10^(-13)`
