Question(b) Show that the HCF and LCM of $x(a+4)$ and $a^{3}+64$ is $a+4$ and $x(a+4)\left(a^{2}-4 a+16\right)$ respectively.

Studdy Solution
Verify the HCF and LCM results.
- The HCF is correctly identified as $(a+4)$. - The LCM is correctly identified as $x(a+4)(a^2 - 4a + 16)$.
Solution: The HCF of $x(a+4)$ and $a^3 + 64$ is $a+4$, and the LCM is $x(a+4)(a^2 - 4a + 16)$.
