Question

an be evaluated one function at a t
$h(x) = 3\sqrt{x} - 7$
$k(x) = 5\sqrt3{x}$
find $k\bigl(h(25)\bigr).$

Explanation:

Step1: Calculate h(25) first

Substitute $x=25$ into $h(x)$:
$h(25)=3\sqrt{25}-7 = 3\times5 - 7$

Step2: Simplify h(25)

$h(25)=15-7=8$

Step3: Calculate k(h(25))=k(8)

Substitute $x=8$ into $k(x)$:
$k(8)=5\sqrt[3]{8}=5\times2$

Step4: Simplify k(8)

$k(8)=10$

Answer:

10
