Hi Guys can someone help solve these

1)
(x^2 + 3) . square root of (2x^3 -5)

2)

[x. square root of (x) - x^2 ] / square root of (x + 2)

thanks!!

this method is beyond the 2 unit syllabus (its 4 unit) but knowing this will certainly give you the edge over other 2unit-ers

take note that i use the rule that the the derivative of Ln[f(x)]=f'(x)/f(x)
