Firstly, I am quite new to indices in mathematics, though I am not sure about using fractions when it comes to pronumerals as well. So, any help is appreciated.
Simplify the following questions:
1. p^6q^4 divided by p^q
2. 8w^10 divided by 2w^4
3. 2x^6 multiplied by 5x, divided by 10x^4
4. (2g^2)^2
5. 20d^8e^6 divided by 2d^2e multiplied by 5d^2e^2
Thank you for your time. I shall be waiting!
remember the rules:
*in dividing polynomials just subtract the exponent the divisor from the exponent of the dividend
*in multiplying say for example just add the
exponents
* when a polynomial like you just get the
square of to then multiply the exponent that is with
.
You are most welcome. Sorry about the typo before, I am new to notation on the computer. I don't have much time, so please be as fast as possible, in half an hour I have to leave (it is due tomorrow morning!!! ).
I have tried my best, and correct me if I am wrong:
1. p^6q^4 divided by p^q
= (pq) ^3
2. 8w^10 divided by 2w^4
= w^12
3. 2x^6 multiplied by 5x, divided by 10x^4
= 13x / 14x
4. (2g^2)^2
= 2g^4 OR g^6 ???
5. 20d^8e^6 divided by 2d^2e multiplied by 5d^2e^2
= d^17 X e^4
I have written down the rules as well to help me in future.
you did the same typo again
no2. 8w^10 divided by 2w^4
= w^12
note that you have
no, you have3. 2x^6 multiplied by 5x, divided by 10x^4
= 13x / 14x
no. princess21 warned you about this also: now finish up4. (2g^2)^2
= 2g^4 OR g^6 ???
again, no (are you sure you are seeing how to apply the rules?)5. 20d^8e^6 divided by 2d^2e multiplied by 5d^2e^2
= d^17 X e^4
i suppose you mean
you have:
Ah, I know, I am terrible at maths. Did you provide the answer under the explanation? I don't yet understand experienced terms like 'polynomial' but I am working on it. I just really need help with this, as it was given as homework and we have never done indices before. The teacher said we had to find out by ourselves.
stop saying that and start trying harder. everything is difficult the first time. learning your ABCs was hard once upon a time.
i only answered the first one completely. the others you have to finish. i put each in a form where you can apply the rules easily. do you see how i got to these forms? try the problems againDid you provide the answer under the explanation?
don't worry about that yet. knowledge of polynomials is not needed here, just follow the rules.I don't yet understand experienced terms like 'polynomial' but I am working on it.
you found it. i told you all you need to know. you are no longer in the dark. just try to pay attention and see where you can apply the rules.I just really need help with this, as it was given as homework and we have never done indices before. The teacher said we had to find out by ourselves.
Sorry for complaining. I'm just a bit stressed. I have been doing maths all day and I have hit an obstacle I can't seem to get past. Do the rules have to be applied in every problem (that's what I do not understand)?
For example:
I don't know how the 8 works or the 2. Can you add it to the indices?
8w^10
------- =
2w^4
yes, you would apply the rules here for w. as far as the 8/2 is concerned, that's just 4
you separate each kind of term as you saw me do, and simplify each. so think of the 8/2 separate and then you have the (w^10)/(w^4). work out each separately, and then multiply them together when done
