Answer 1

y= ( 5x^2 +6)( 2 x^3 +4)

y'= 10 x( 2 x^3 +4) + 6 x^2( 5 x^2 +6)

= 20 x^4 + 40 x + 30 x^4 + 36 x^2

= 50 x^4 + 36 x^2 +40 x

= x( 50 x^3 + 40 + 36 x)

2) y= √x ( x^2 + 7)

1/2√x ( x^2 + 7) + 2 x( √x)

( x^2 + 7)/ 2√x. +. 2 x^3/2

3) y= x^2 +3)( x^4-9)

2x ( x^4 -9) + 4 x^3( x^2 +3)

2 x^5 - 18 x + 4 x^5 + 12 x^3

6 x^5 + 12 x^3 - 18 x

6x ( x^4 + 2 x^2 - 3)
