You can put this solution on YOUR website!
+sqrt%2881x%5E8y%5E12z%5E20%29+
Remember that everything that leaves a square root is the number or variable the square root is squaring.
+sqrt%28%289%5E2%29%28%28x%5E4%29%5E2%29%28%28y%5E6%292%29%28%28z%5E10%29%5E2%29%29+
When an exponent is raised to a power, you simply multiply the current exponent by the power it is raised to.
Example: +%28%28x%5E2%29%5E4%29 is the same as +x%5E8+
Therefore, the final answer is:
+9x%5E4y%5E6z%5E10+
