Question
Perform the indicated operation and simplify. Assume all variables represent positive real numbers.$$\frac{\sqrt{21 z^{18}}}{\sqrt{3 z^{13}}}$$
Step 1
The square root of 21 divided by the square root of 3 is 7. The square root of \(z^{18}\) divided by the square root of \(z^{13}\) is \(z^{5}\). So, we have: $$\frac{\sqrt{21 z^{18}}}{\sqrt{3 z^{13}}} = 7 z^{5}$$ Show more…
