Explanation:

Given : Number in scientific terms
`5.27* 10^(21)`

To find : What is number expressed in standard notation?

Solution :

The standard notation of a number is the expanded form of scientific notation.

The number we have given is
`5.27* 10^(21)`

Remove the decimal,

`(527)/(100)* 10^(21)`

`527* 10^(21-2)`

`527* 10^(19)`

i.e. writing 19 zeros after the number,

`5270000000000000000000`

Therefore, The required number in standard notation is

`5.27* 10^(21)=5,270,000,000,000,000,000,000`
