Question

Help me please?
Simplify the following:

Answer 1

\[\sqrt{108x4y9}\]

Answer 2

I think you mean?
\[\sqrt{108x^4y^9}\]
find a perfect square factor in 108 first.
You can split 108 to 36 and 3, and 36 is a square. So take the square root of 36 and put it outside the square root.
\[6 * \sqrt{3x^4y^9}\]

Answer 3

than, take the square root of even exponents out. Odd exponents, leave one inside.
\[6 * x^2 * y^4 \sqrt{3y}\]

Answer 4

so \[6x^2y^4\sqrt{3y}\]
