2. Okay so I thought to rewrite this as:

∫(8x^2 + 8)(x^-1/2)dx

= ∫(8x

^{3/2}+ 8x

^{-1/2}

= (2*8x

^{1/2}+ (2/3)*8x

^{-3/2}) |3 to 9

= (16)(9^(1/2)) + (2/3)(8)(9^(-3/2)) - [(2)(8)(3^(1/2)) + (2/3)(8)(3^(-3/2))]

= 48 + .19753 - (27.71 + 1.0264)

= 19.46113

This answer is wrong... I can't find where I made my mistake, though! :/

Please help!

Thank you so much! :)
