Answer:

3x^2y\sqrt{2\cdot y}

Step-by-step explanation:

We have been given an radical expression. We are asked to simplify our given expression.

\sqrt{18x^4y^3}

We can rewrite terms of our given function as:

\sqrt{18\cdot x^4\cdot y^3}

\sqrt{2\cdot 9\cdot x^4}\cdot y^2\cdot y}

\sqrt{2\cdot 3^2\cdot (x^2)^2\cdot y^2\cdot y}

Using radical rule \sqrt[n]{a^n}=a, we will get:

3x^2y\sqrt{2\cdot y}

Therefore, the simplified form of our given expression would be 3x^2y\sqrt{2\cdot y}.

Combine the radicals. 3√5-8√5+2√5
weeeeeb [17]

Answer:  -3\sqrt{5}

-3 times the square root of 5

=============================================

Explanation:

Let x = \sqrt{5}

Replace all the root 5 terms with x and we go from

3\sqrt{5}-8\sqrt{5}+2\sqrt{5}

to

3x-8x+2x

From here, combine like terms to get

3x-8x+2x = -5x+2x = -3x

and the last thing to do is replace the x with sqrt(5)

-3x = -3\sqrt{5}

Meaning that,

3x-8x+2x = -3x

3\sqrt{5}-8\sqrt{5}+2\sqrt{5} = -3\sqrt{5}
