Laws of Indices - Part 1 | Algebra | Maths | FuseSchool

The laws of indices make complex sums involving powers much easier to handle.

There are six 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 four laws in this video, and then will cover fractional and negative indices in a different video.

These are the first four 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.

She literally explained this more than my math teacher did

[samanthawhiting]

can I just say that these classes are the only thing that's really helping me in online classes

[welpwelp]

Who else is here cause of online classes? XD

[AllenUmoh-lc]

A lot easier to understand, thanks.Also loving the accent

[joygitsarangi]

(a) 6a to the power 10
(b)x to the power 5 y to the power 3
(c) 2w to the power 7 x to the power -3
(d) 8a to the power 12 b to the power 15
(c) 1

liked, easy explanation, out of this world teacher/narrator.

[syedaareeba]

Thanks alot!
This made my concept alot more clearer and I am pretty fluent in this topic now.

[gerrardlee]

if she was my maths teacher i wouldn't of skipped a single maths class

[SaliniSnair-eyxb]

this is not only useful for small students but also for higher secondary students

[akicchi_]

[seddk]

Who else is here cuz his teacher is bad at explaining lessons XD

[onyekachiiheama]

Beautiful explanation of the topic, we need better teachers like this in my school 😂😂 plus 1 sub btw

[Iucebowel]

Raising powers was really buggin me out, thanks!

[MistaYo]

well we all know why we are here















To learn maths duh.

[PAlexSCole]

Thanks for adding more knowledge to what I already have.

[JuliannaMagekon]

I almost got everyone correct, but instead I got the letter c wrong, it's fine we all learn from our own mistake, and thanks to you for the explanation.❤❤❤

FuseSchool-Global Education is FREAKING BEST

[ceona_purple_army]

This help me a lot in multiplying indices what happens if a number is negative

[harjitkaur]

Can u please make a video for complex questions of indices and how to solve them
