Solve (a^(21)⋅a^(-12))/a^(6)

Evaluate

\frac{a ^{21} \times a ^{- 12}}{a ^{6}}

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

\frac{a ^{21} \times a ^{- 12}}{a ^{6}} = 0

Find the domain

More Steps

\frac{a ^{21} \times a ^{- 12}}{a ^{6}} = 0, a \neq = 0

Calculate

\frac{a ^{21} \times a ^{- 12}}{a ^{6}} = 0

Multiply the terms

More Steps

\frac{a ^{9}}{a ^{6}} = 0

Divide the terms

More Steps

a^{3} = 0

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

a = 0

Check if the solution is in the defined range

a = 0, a \neq = 0

Solution

a \in \emptyset
