6.000 - 4.000 = 2.000
It is a very simple equation. The easiest way to remember it would be to look at the first two numbers. 6 subtract 4 equals 2. So when you see this equation, simply for starters do 6 subtract 4, which equals 2, and then add a decimal place and the 3 zeros at the end. Does that make sense? Please let me know whether this was useful to you or not, and if you have any further questions please feel free to ask so on comments. Thank you!
The property of exponents says that when you divide two exponents with the same base, you can keep the base and subtract the exponents. So you can do 18-3, which is 15, so it would be 15 to the 15th power
