I need help on Algebra

Can someone teach me how to solve the following problems in an easy to understand way? Appreciate any help!

Simplify and express with positive indices

6√a^4b x^6 *(a^2/3 x^-1 )

(16x^2/y^-2)^1/4

-
simplify √a^4 = √(a²)² = a²

6a²b x^6 *(a^2/3 )x^(-¹)

adding a² and a^²/³ =a(²+²/³) = a^(8/3)
adding
x^6 x^(-¹)= x^(6-1)=x^5
then put it back together

next
(16x^2/y^-2)^1/4
distribute the exponent (1/4)

(16)^1/4 (x²)^1/4 / (y-²)^1/4

= 2 x^( 2/4) /y^(-2/4) = 2 √x√y = 2√(xy)

You are welcome my dear.

[(16x^2)/(y^-2)]^(1/4)
= (16 x^2 y^2)^(1/4)
= (2^4 x^2 y^2)^(1/4)
= 2^(4/4) * (xy)^(2/4)
= 2 √xy
