Simplify:(picture)
and please show your work so that i can understand how to simplify. thanks

Answer 1

√20x *√5x3 - We can involve the action under the square root, because we have a multiplication of two square root elements.


`\sqrt{20x*5x^(3)} = \sqrt{20*5 x^(4) } = √(100) *x^(2) = 10x^(2)`

We are using the fact, that the multiplication of the square roots is alternating.

Answer 2

The answer is 100x2 because 20x5= 100 and the power of 2 is alone, so that’s the answer.
