Question

1 Read all choices carefully, since several answers look correct but are not: Simplify sqrt(5) / sqrt(35), rationalizing the denominator to put your answer in "simplest form." Your answer could be written as:

sqrt(175) / 35

sqrt(5*35) / 35

sqrt(7) / 7

1 / sqrt(7)

sqrt(35) / 35

2 Read all choices carefully, since several answers look correct but are not: Simplify 4throot(2) / 4throot(3x), rationalizing the denominator to put your answer in "simplest form." Your answer could be written as:

4throot(162x^4) / (3x)

4throot(54x^4) / (3x)

4throot(54x^3) / (3x)

4throot(18x^2) / (3x)

4throot(6x) / (3x)

3 Read all choices carefully, since several answers look correct but are not: Simplify cuberoot(3(x^2)y) / cuberoot(5xy^2), rationalizing the denominator to put your answer in "simplest form." Assume x and y are not 0. Your answer could be written as:

cuberoot(3x/(5y))

cuberoot(75xy^2)/(5y)

cuberoot(3x)/cuberoot(5y)

cuberoot(15(x^2)(y^2)) / (5y^2)

cuberoot(15xy) / (5y)
