Question

Which of the following is a simpler form of the radical expression sqrt 27x^4/75y^2?

Answer 1

In order to simplify this expression, this is how to do it.

I assume that the expression is like this one:
sqrt (27x^4 / 75y^2)

so
sqrt ( 9*3 x^4 / 25*5y^2)
= (3x2 / 5y ) * sqrt(3 / 5)

So, the final expression or the simpler expression based from the given question is (3x2 / 5y ) * sqrt(3 / 5)

Answer 2

Lesson 1 Unit 2: Roots and Radical Expressions

1 = a (no real root)

2 = c (-0.05)

3 = c (6lg^3l)

4 = d (5x^7y^8)

5 = a (3x^2/5y)

5/5 100%
