Search results “Rules of indices”

The laws of indices make complex sums involving powers much easier to handle.
There are 6 laws we need to know and understand: how to multiply and divide with indices, raising a power to a power, what a power of 0 means, negative indices and fractional indices.
We will look at the first 4 laws in this video, and then will cover fractional and negative indices in a different video.
1) When we multiply indices, we add the powers together, provided they have the same base number.
2) When we divide indices, we subtract the powers. But again, the base number must be the same.
3) When a power is raised to a power, we multiply the powers.
4) Anything to the power of 0 is 1.
These are the first 4 laws of indices.

List of all indice laws
Rule 1 x^0 = 1 (except for 0^0)
Rule 2 x^-n = 1 / (x^n)
Rule 3 x^n * x^m = x^(n+m)
Rule 4 x^n / (x^m) = x^(n-m)
Rule 5 (x^n)^m = x^nm
Rule 6 (x^n/m) = msqrt(x^n)

In this video, discuss about the basic law of indices, and provide few example from pass year questions. Hope this video is able to make understand more about indices. Because it is very important when you go for Logirithmic. Besides that, this video is suitable for SPM maths and add maths students, due to the content is easy to understand for everyone ^_^ Anyways, If you would like to have more interaction with me, or ask me more question, or suggest some chapter u want to learn, please add the facebook page at "y=mx+c" or www.facebook.com/maths.video

In this video we are going to look at what happens with negative indices and fractional indices. You should already know the other 4 ‘Laws of Indices’ but if you have forgotten, have a look at them first. For negative indices, we drop whatever numbers and/or letters have the negative indice (also known as power or exponent) down to the denominator and make the indice (power or exponent) positive. E.g. x^(-2) is the same as 1/x^2 where it was negative when a numerator and becomes positive as a denominator. Fractional indices: an indice of a 1/2 is the same as square root. An indice of 1/3 is the same as cube root. An indice of 1/4 is the same as 4 root. But what if the numerator isn’t one? An indice of 3/2 means square root the number and then cube it. An indice of 2/3 means to cube root and then square it. So the denominator is still the root of the number, and the numerator then raises the root to the power. Fractional law of indices = power / root. Power makes things bigger so is on top, and root makes things smaller so is on the bottom. I always do the root first and then the power second to keep the numbers small, but you can actually do them in either order. Although I really recommend rooting first and doing the power second. Some examples: 25^3/2 means to square root 25 and then cube the answer. 25^3/2 = 5^3 = 125.
