Answer 1

Answer 2

`1color(red)(70,000,000,000) = 1.7 xx 10^color(red)(11)`

Explanation:

In scientific notation there must be only ONE digit before the decimal comma. The power of 10 indicates how many placeholders there are - which shows how many times the digits have been multiplied or divided by 10.

`1color(red)(70,000,000,000) = 1.7 xx 10^color(red)(11)`
