indices

Does anyone get what this means
5n / 5n
I have to find the numerical value of it and it has to be an actual number without any fractions or indices
Also, what does the / mean in it?

/ means division.

So what is (5n) divided by (5n) ??

I dont get why they didn't use a division sign for that question when they did for others..
and yeah I have no idea how to work it out because I don't know what 5n means

/ is common online because the division sign ÷\div is just not as simple to type.

More often though, we just write a fraction to symbolise division. For instance, ‘x’ divided by ‘y’ is xy\dfrac{x}{y}.

As for your question, 5n is just an algebraic way of expressing any number you choose. The ‘n’ here essentially means ‘any number you want goes here’

So n is just any number.
Which means 5 lots of it, ie 5n, is just any number as well.


I think what the question is trying to get at is for you think about what value do we get when we divide any number by itself. The answer is a nice simple number.

One. Without the n.

Think about it this way:

5n5n\dfrac{5n}{5n} can be split up into 55\dfrac{5}{5} ×\times nn\dfrac{n}{n}

55\dfrac{5}{5} gives 11 and nn\dfrac{n}{n} also gives 11

1×1=11 \times 1 = 1 therefore the answer is 1 not 1n
