Answer:

$5xy^3 \sqrt{3x}$

Step-by-step explanation:

The radical $\sqrt{75x^3y^6}$ can be simplified by breaking it down into factors and removing the perfect squares from inside the radical.

$\sqrt{75x^3y^6} =\sqrt{3*25*x^2*x*y^6} =5xy^3 \sqrt{3x}$

25 is a perfect square and is 5 outside the radical.

$x^2$ is a perfect square and is x outside the radical.

$y^6$ is a perfect square and is $y^3$ outside the radical.

12а + 7x - За – 2х what's the answer<br>

Troyanec [42]

9a-5x

step by step explanation:

you can only add and subtract numbers that have the same variables.

12a and 3a are related because there variable is both a.

when u subtract 12a-3a you get the answer of 9a using subtraction.

7x and -2x are the second pair of related terms because they also have the same variable (x)

7x-2x is 5x using subtraction.

put the expression together:

9a-5x

hope this helps!
