Question

Shawn said that in standard notation,
7.142 x 107 will have 7 zeros after the
2 because the exponent is a 7. Is he
correct? Why or why not?

Answer 1

Answer:

Shawn is incorrect.

Step-by-step explanation:

The decimal is moving 7 places to the right.  The 2 is the third digit, so there will be 4 0s after it.
