7 sqrt(2) x^(2) y^(3) z

Explanation:

We have: sqrt(98 x^(4) y^(6) z^(2))

Let's express 98 as a product:

= sqrt((14 cdot 7) x^(4) y^(6) z^(2))

= sqrt((2 cdot 7 cdot 7) x^(4) y^(6) z^(2))

= sqrt(2 cdot 7^(2) x^(4) y^(6) z^(2))

= sqrt(2) cdot 7 cdot x^(2) cdot y^(3) cdot z

= 7 sqrt(2) x^(2) y^(3) z
