Answer 1

^^

Answer 2

solve \(n+4=9\) for \(n\) in one step

Answer 3

\[\frac{8^{n}}{y^{-4}}=8^{n+4}=8^9\] making \(n+4=9\)

Answer 4

thats confusiing

Answer 5

yes, i know, this question is confusing
rather silly too
when you divide, you subtract the exponents
so \[\frac{8^?}{8^{-4}}=8^{?+4}\]

Answer 6

you know the answer is \(8^9\) cause that is what it says
that means \(?+4=9\) so \(?=5\)

Answer 7

the check is that \[\frac{8^5}{8^{-4}}=8^{5-(-4)}=8^{5+4}=8^9\] as needed

Answer 8

honestely i still dont get it

Answer 9

i know i sound dumb im sorry but math is hard for me

Answer 10

yeah i don't really know any other way to say it though
it is a question about properties of exponents, but it is asked in a strange way

Answer 11

here is what you are supposed to know
when you divide, you subtract the exponents

Answer 12

so for example \[\frac{8^{10}}{8^4}=8^{10-4}=8^6\]

Answer 13

and \[\frac{8^5}{8^{-4}}=8^{5-(-4)}=8^9\]

Answer 14

Ohhhh so its 10 -4=6

Answer 15

right in my example, not in your question though

Answer 16

oh :/

Answer 17

in your question you had to fill in the blank for the exponent in the top

Answer 18

so you had to think of a number that, when added to 4, gives 9
that number is 5

Answer 19

oh

Answer 20

that makes since.
