Define negative exponent rule11/26/2023 And when so many kids are criticizing the same stuff the same way almost everywhere, we need to step back and consider that maybe the math curriculum in secondary schools is so flawed that even adolescents can point out the asinine. However, there isn't much you can do for a student who does not see how this will be applicable anywhere else in life. ![]() ![]() And that's a lot of pressure (especially for that demographic). And it also goes often unsaid that it is also your job to get them ready for 'the test' which will be one of the largest factors that determine their path in life. This may be somewhat disappointing as it is your job to teach these things and hopefully imbue understanding. In fact, instead of doing this in class, you could make this a hand-out for the interested student (this might help the most amount of students). Option 2: give them the 'real' definition at the risk of confusing most of them, intriguing a couple, but still telling them that this is how it is because a lot of people wanted those nice properties. But I know I always appreciated bluntness from the teacher, so that I could shift my brain into 'as is' mode. Since the logarithm is not defined for negative numbers, the answer is: x. You can lighten this approach by showing them patterns, like the ones already mentioned, which hint at why this should be the way things are. Option 1: just tell them this is how things are and they just need to memorize the rules. So in my opinion, there are two ways to teach exponentiation to high schoolers. 10^9 means: multiply 10 together 9 times. 10^5 means: multiply 10 together 5 times. Start by asking (either rhetorically or Socratically): what is exponentiation meant to mean? It means multiplying by a number multiple times. That said, this is my personal favourite explanation.) Different explanations will work better for different students. To decrease the powers, we need to briefly understand the concepts of. ![]() (First of all, I’d echo comment: there not one best way to explain things. We can figure this out by dividing multiple times to decrease the power value until we get to zero.
