Answer 1

NONE of these statements are true

Answer 2

a) False

`(d)/(dx) (f(x).g(x)) = f'(x).g(x) + g'(x).f(x)`

b) False

`(d)/(dx) ( \sqrt{x {}^(2) + x} ) {}^(2) = \frac{2x + 1}{2 (\sqrt{x {}^(2) + x}) {}^(2) } = \frac{2(2x + 1)(x {}^(2) + x) }x²+x = \frac{(2x + 1)(x { }^(2) +x)}x²+x`

Im assuming this is an absolute value

c) True

`(d)/(dx) ( √(f(x)) ) = (f'(x))/(2 √(f(x)) )`
