Question

whats z^2z^4/z^3Z^-1

Answer 1

\[z ^{2} z ^{4}/z ^{3}z ^{-1}\]

Answer 2

\[z^2z^4/z^3z ^{-1}= z^1/z^3 = 1/z^2\]

Answer 3

u study number complexe

Answer 4

how did you get z^1 on the top and z^3 on the bottom?

Answer 5

@dinamix

Answer 6

isn't it 2+4 which is 6 and the 3+ (-1)=2

Answer 7

z^4/z^3 = Z^(4-3) = Z^1

Answer 8

how're you getting those numbers though

Answer 9

and z^2/z^-1 = z^(2-(-1)) =z^3

Answer 10

ohhh okay i see what you did there! this problem was so easy but it wars confusing for second thanks for your help

Answer 11

its when u see Basis of divided like this u have make difference

Answer 12

\[z^x * z^y = z ^{x+y}\]

Answer 13

\[z^x/z^y = z^{x-y}\]
