Given the expression
as
similarly
Convert element to a decimal form
so
Thus, the expression becomes
Hence,
<em>converting -86999999999.9941 in a scientific notation</em>
In order to make our job easier we will remove the sign "-" from number -86999999999.9941 (we will write "-" at the final solution). So after this step we have:
<em>−86999999999.9941 ⟶ 86999999999.9941</em>
<em></em>
In order to write number 86999999999.9941 in scientific notation, we need to move the decimal point from its current location (black dot) to the new position such as:
<em>8.6999999999.9941</em>
<em />
So, we need to move the decimal point 10 places to the right.
This means that the power of 10 will be positive 10.
Now we have that the
Number part = 8.69999999999941 and
Exponent part = 10
Thus, we conclude that:
−86999999999.9941 = − 8.69999999999941 × 10¹⁰
