$x(1,4,5)=4$
$y(1,4,5)=100$

$z_s=z_xx_s+z_yy_s=(4x^3+2xy)(1)+x^2(tu^2)$
$z_s(1,4,5)=1,024,000$

$z_t=z_xx_t+z_yy_t=(4x^3+2xy)(2)+x^2(su^2)$
$z_t(1,4,5)=1,331,200$

$z_u=z_xx_u+z_yy_u=(4x^3+2xy)(-1)+x^2(2st)$
$z_u(1,4,5)=-450,560$

PLEASE ANSWER + BRAINLIEST!! Factor completely. 4k - 20k^9 = 3b^2 - 108 =

Neporo4naja [7]

$4k-20k^9=4k(1-5k^8)=4k\left[1^2-(k^4\sqrt5)^2\right]\\\\=4k(1-k^4\sqrt5)(1+k^4\sqrt5)=4k\left[1^2-(k^2\sqrt[4]5)^2\right](1+k^4\sqrt5)\\\\=4k(1-k^2\sqrt[4]5)(1+k^2\sqrt[4]5)(1+k^4\sqrt5)\\\\=4k\left[1^2-(k\sqrt[8]5)^2\right](1+k^2\sqrt[4]5)(1+k^4\sqrt5)\\\\=4k(1-k\sqrt[8]5)(1+k\sqrt[8]5)(1+k^2\sqrt[4]5)(1+k^4\sqrt5)$

$3b^2-108=3(b^2-36)=3(b^2-6^2)=3(b-6)(b+6)$

$Used:\ (a-b)(a+b)=a^2-b^2$
