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.
These are the first 4 laws of indices:
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.
