Correct Answer: 50

Solution : Given:
(10 C 4) A (4 C 4) B 6 = ?

After replacing the letters with mathematical signs, the equation becomes –
= (10 × 4) + (4 × 4) – 6
= 40 + 16 – 6
= 56 – 6
= 50

Correct Answer: 18

Solution : Given, $k^4+\frac{1}{k^4}=47$
Adding 2 on both sides,
⇒ $k^4+\frac{1}{k^4}+2=47+2$
⇒ $(k^2)^2+\frac{1}{(k^2)^2}+2\times k^2\times \frac{1}{k^2}=49$
⇒ $(k^2+\frac{1}{k^2})^2=49$
⇒ $k^2+\frac{1}{k^2}=7$
Again adding 2 on both sides,
$k^2+\frac{1}{k^2}+2=7+2$
⇒ $(k+\frac{1}{k})^2=9$
⇒ $k+\frac{1}{k}=3$
cubing both sides, we get,
⇒ $k^3+\frac{1}{k^3}+3×k\times \frac{1}{k}(k+\frac{1}{k})=27$
⇒ $k^3+\frac{1}{k^3}+3×3=27$
$\therefore k^3+\frac{1}{k^3}=27-9=18$
Hence, the correct answer is
