Answer:
673,210,000
Step-by-step explanation:
The given number is :
N = 6.7321 × 10⁸
We need to write it into the standard form.
10⁸ = 100000000
It can be calculated as follows :
6.7321 × 100000000 = [tex]\dfrac{67321 }{10000}\times 100000000[/tex]
= 673,210,000
So, the standard form of the given number is 673,210,000. Hence, the correct option is (c).
