Question

In scientific notation, 130,000,000 + 17,000,000 = ?

Answer 1

Answer: 1.47 * 10^8

Step-by-step explanation:

First, let's add in standard form to avoid confusion

130,000,000

+17,000,000

------------------------

147,000,000

Since scientific notation expects the 1st base to be greater than 1 but less than 10, 147,000,000's first base in SCI notation should be 1.47.

Now to complete: 1.47 * 10^8
