Ok. Let's start there then.

A number written in scientific notation consists of two parts that are multiplied together.
1. A number from 1 to 10 , including 1 but not 10.
2. 10 raised to an integer.

To convert 260,000 to scientific notation, find the part of the 260,000 that is a number between 1 and 10.
That would be 2.6
Now you need to see what power of 10 you need to multiply 2.6 by to get back to 260,000.
