Nevermind, I went about this in completely the wrong way and figured it out.
(4 * 2) * (a^(3/2)+(1/2)) = 8a^2
The question is: Simplify (4a^(3/2)) * (2a^1\2))
The answer the book gives is: 8a^2
My work includes:
1. (4a^(3/2)) * (2a^1\2))
2. (sqrt(4)^3) * (sqrt(a)^3) * sqrt(2) * sqrt(a)
3. (sqrt(4)^3) * (sqrt(a)^4 * sqrt(2)
4. 2^3 * a^2 * sqrt(2)
Thus: 8a^2 * sqrt(2)
Is the book wrong, or how do I get rid of that sqrt(2)?
Thanks
