For non-negative a and b, 
$ \sqrt{a^2b^4} = ab^2 $

Now square the first expression and raise the second expression to the 4th power and multiply them together to find what ab^2 is equal to.

i dont how to solve it

mathstudent55 · Answer

We need to find a and b^2, and then multiply them together.

$ \sqrt{a} = c\sqrt{d} $

Square both sides:

$a = c^2d$ We have a.

$ \sqrt{b} = c\sqrt{d} $

Raise both sides to the 4th power to find b^2:

$ (\sqrt{b})^4 = (c\sqrt{d})^4 $

$ b^2 = c^4d^2 $ Now we have b^2.

Now we multiply a by b^2:

$c^2d \times c^4d^2 $

$c^6d^3 $
