#1**+1 **

Uh so I know that it is used with powers, but I don't know how how to solve it.

Scientific notation is usually for writing gigantically enormous numbers, or teensy miniscule numbers.

It is written as \(a \cdot 10^x\).

\(a\) can be a integer or decimal between 0 and 10 (non-inclusive).

Some examples:

\(31,469 = 3.1469 \cdot 10^{4}\)

\(142000000000000000 = 1.42 \cdot 10^{17}\)

If a number is less than 1, it is written as 10 ^ {negative number}.

\(0.02 = 2 \cdot 10^{-2}\)

\(0.00000000103 = 1.03 \cdot 10^{-11}\)

\(31.1 \cdot 10^{16}\) isn't scientific notation, as 31.1 can further be divided by 10 to become \(3.11 \cdot 10^{17}\),

This is a rather short summary of scientific notation, but I hope you can understand some part of it now.
