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
