Question

Is the answer the first or last one? Picture is below.
I know its the first or last one but I cant figure out which one.

Answer 1

Thanks! I kind of just needed a second opinion because I'm not sure.

Answer 2

what is another way of writing 1/11^8 ?

@katrynakay - that is not correct

Answer 3

@Caitlyn_Morgan note - @katrynakay is not correct

Answer 4

11^12 is a very large number

in the original oyu are DIVIDING by 11^8 - so oyu might expect a SMALL answer

Answer 5

Soo.. Um. Whats the answer then? I'm pretty sure it the first or last one.. :p

Answer 6

first answer this:
what is another way of writing 1/11^8 ?

Answer 7

I don't know. I'm really bad with exponents.

Answer 8

Well that question is a basic element of exponents :

Here is the rule:
\[\frac{ 1 }{ x ^{n} }= x ^{-n}\]

so what is
\[\frac{ 1 }{ 11^{8}}\]

Answer 9

Out of the answers would it be 11^4?

Answer 10

I'm not interested in your guesses.

If oyu don't want to learn about exponents then you will forever be "really bad with exponents"

Try to answer my question - it will guide you to the answer FOR YOURSELF and soon you will NOT be "really bad with exponents"

Answer 11

11^-8? Based on the rule you mentioned is that it?

Answer 12

Perfect

Answer 13

So

\[\frac{ 11 ^{-4} }{ 11^{8} } = 11^{-4}\times 11^{-8}\]

Answer 14

and the rule is
\[x ^{a} \times x ^{b} = x ^{(a+b)}\]

Answer 15

So it would be 11^4

Answer 16

Why?
what is -4 + -8 ??

Answer 17

-12 sorry I missed one of the negatives

Answer 18

Well done.

so you have 11^-12

What is another way of writing this? (you did it above....)

Answer 19

1/11^12?

Answer 20

That's right - so now you are on your way to NOT being really bad with exponents :-)

Answer 21

Thank you! That was very helpful! :D

Answer 22

NP

But please do not take all answers here at face value - there are VERY many incorrect answers posted!
