30 x 10^6 in scientific notation

Question

The question 30 x 10^6 in scientific notation. Would it turn into .3 x 10^5 or am I wrong? I'm doing this with a friend right now, so could I get a answer quick???

Answer 1

30 x 10⁶ is equal to 30 with 6 additional zeros after it: 30,000,000.

 

3 x 10⁵ is equal to 3 with 5 additional zeros after it: 300,000

 

So no, 30 x 10⁶ is not the same as 3 x 10⁵.  Think of it this way 30 = 3 x 10, so:

 

30 x 10⁶ = (3 x 10) x 10⁶ = 3 x 10⁷
