I really need help wih these two!!!

Question

Rewrite using radicals: (x^(3/4))(y^(1/4))
 

cuberoot(x^4)*sqrt(x^(1/2))

cuberoot(x^4)*y^4

cuberoot(x^4)*4throot(y)

4throot((x^3)y)

sqrt((x^(3/2))y)
 

Rewrite using rational exponents: sqrt((3xy)^4)
 

(3xy)^(1/2)

(xy)^(3/4)

3(x^2)(y^2)

9(x^2)(y^2)

81(x^2)(y^2)

Answer 1

Look at this law:

 

a^m/n = ⁿ√a^m

 

So:

 

x^3/4 = ⁴√x³

 

Now you can do the rest!
