Question

z^-7/z^-4
show step how to solve

Answer 1

So in this problem you would need to subtract the exponents since they have the same base which is z.

Answer 2

ok i got 2^3

Answer 3

Answer 4

Where did you get a 2? The base is a z.

Answer 5

oh my bad i ment z^3

Answer 6

\[\frac{ z ^{-7} }{ z^{-4} }\]Take the exponents.
-7 & -4
Now subtract them.
-7-(-4) = -3
-3 is now your exponent.
\[z^{-3}\]But negatives can't be with exponents so in order to get rid of it, you would have to flip the whole "z^-3". The final answer should look like this: \[\frac{ 1 }{ z^{3} }\]
