1. Solution to the radical function sqrt(12x+1) = 1 is x = 0

True or False I think it is true according to my calculations

2.Solve x = sqrt(8x)

8x = x^2

x^2 - 8x = 0

x(x-8) = 0

x = 0

x-8 =0

x=8

the only solution is x = 0, correct or no?

3. Simply (3x^2y^-2)^-2/9x^-5y

a.xy^3

b. xy^3/3

xy^3/9

d. xy^3/81

I think it is xy^3/81 but I'm not sure of my calculations

4. Solve 4sqrt(6x-2)>4

a. 1/3<=x<43

b. 1/3<x<43

x>=43

x>43

I think x>43

Thank you
