Question

102,410,000,000,000,000,000,000,000 in scientific notation round to two digits after the decimal

Answer 1

We have a big integer and want to write in scientific notation.

To do this we need to count how many places we need to move the decimal point.

In this case we need to move the decimal point to left so the exponent of 10 will be positive.

So,

`\begin{gathered} 102,410,000,000,000,000,000,000,000=1.0241\cdot10^(29) \\ \text{Round to two digits after the decimal:} \\ 1.02\cdot10^(29) \end{gathered}`

We move the decimal point 29 places to left so the exponent of 10 is 29.
