Best ResponseYou've already chosen the best response.0The question is \[\frac{15^{18}}{15^{3}}\] right?

Best ResponseYou've already chosen the best response.0OK, the important thing to remember about exponents is that they usually represent multiplying the same thing over and over. So for example, \[15^3 = 15 \times 15 \times 15\]. where the exponent 3 tells me to multiply 15 three times. Does that make sense as an example?

Best ResponseYou've already chosen the best response.0Of course, that's the next step. :) I'll help you figure it out by asking you a couple questions. It's not too hard. :) Let's think about the top part of the fraction. How many times do I multiply 15 when I have an exponent of 18?

Best ResponseYou've already chosen the best response.0There are eighteen 15s on top, and three 15s on the bottom. There's going to be cancellations!

Best ResponseYou've already chosen the best response.0Good, we get to cancel three 15s, which leaves us with fifteen 15s on top.

Best ResponseYou've already chosen the best response.1Dividing the two is also equal to\[15^{183}\] It will get you the same answer.

Best ResponseYou've already chosen the best response.0The final answer is that we have fifteen 15s multiplied together. This is the same as \[15^{15}\] we are done!
