Question

What is 11,900,000,000 written in scientific notation?

A.1.19×1010

B.11.9×1010

C.1.19×1011

D.11.9×1011

Answer 1

The correct answer is A.

Explanation:

Scientific notation has to be a number between 1 and 10, so we know b and d are out. Then, you have to count how many places you'd have to move to get to the end of the number. It's 10 jumps, so the correct answer would be 1.19*10^10.

Hope this helps!
