Solve z^-7/z^-9 - ScanMath

Evaluate

\frac{z ^{- 7}}{z ^{- 9}}

To find the roots of the expression,set the expression equal to 0

\frac{z ^{- 7}}{z ^{- 9}} = 0

Find the domain

More Steps

\frac{z ^{- 7}}{z ^{- 9}} = 0, z \neq = 0

Calculate

\frac{z ^{- 7}}{z ^{- 9}} = 0

Divide the terms

More Steps

z^{2} = 0

The only way a power can be 0 is when the base equals 0

z = 0

Check if the solution is in the defined range

z = 0, z \neq = 0

Solution

z \in \emptyset
