</span>Give the scientific notation of 8.7 billion.
8.7 billion = 8 700 000 000
Scientific notation is the process of multiplying the given number by 10 to the
power of n.
Since billion has 9 zeros that’s equals
to 10^9
=> 8.7 x 10^9
let’s try solving this
=> 8.7 x (10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10)
=> 8.7 x 1 000 000 000
=> 8 700 000 000
Thus, our scientific notation of 8.7 billion is 8.7 x 10^9</span>
