Answer:
\(20x^{10}\)
Step-by-step explanation:
Given is a number as
\(400x^{20}\)
We are to find the square root of this expression.
WE can find square root for constant separately and x term separately and multiply both to get the square root
\(\sqrt{400} =20\\\sqrt{x^{20} } =x^{10}\)
Hence square root
=\(20x^{10}\)
