We are given expression: 
Let us distribute 3/8 over exponents in parenthesis, we get


We can get x and y out of the radical because, we get whlole number 1 for x and y exponents for the mixed fractions.
So, we could write it as.

Now, we could write inside expression of parenthesis in radical form.
![xy\sqrt[8]{2x^{3}x^4y^7}](https://tex.z-dn.net/?f=xy%5Csqrt%5B8%5D%7B2x%5E%7B3%7Dx%5E4y%5E7%7D)
Because b^6 is present in both terms, we can factor it out.
b^6(7 + 12)
Combine like terms.
b^6(19)
Rearrange.
19b^6 is the fully simplified form of the given expression.
This can vary, some shapes have different area formulas, here are some basic formulas I can give you:
Circle: A =


Triangle: A =

Square: A =

Rectangle: A = L*W
