Greetings. I was just wondering if someone could take a look and tell me I did the following correctly:(adsbygoogle = window.adsbygoogle || []).push({});

1)

y=8x^4-5x^2-2/4x^3

(32x^3-10x)(4x^3)-(12x^2)(8x^4-5x^2-2)/(4x^3)^2

128x^6-40x^4+96x^6-60x^4-24x^2/(4x^3)^2

224x^6-100x^4-24x/16x^6

4x(56x^5-25x^3-24)/16x^6

y’=56x^5-25x^3-24/4x^5

2) y=sqroot 5x - sqroot x/5

y=(5x)^1/2 - (x/5)^1/2

y'=1/2(5x)^-1/2 (5) -1/2(x/5)^-1/2 (1/5)

y'=2/5(5x)^-1/2 -1/10(x/5)^-1/2

y'=2/5sqroot(5x) - 1/10(sqroot x/5)
