Explanation: 
Another Explanation (5):
f(x) = 2x⁴ - 4 এবং g(x) = \(\sqrt{\frac{x-2}{\sqrt{2}}}\) হলে, fog(5) এর মান নির্ণয়:
প্রথমে g(5) এর মান বের করি:
g(5) = \(\sqrt{\frac{5-2}{\sqrt{2}}} = \sqrt{\frac{3}{\sqrt{2}}}\)
এখন, fog(5) = f(g(5)) = \(f(\sqrt{\frac{3}{\sqrt{2}}})\)
f(x) = 2x⁴ - 4, তাই
\(f(\sqrt{\frac{3}{\sqrt{2}}}) = 2(\sqrt{\frac{3}{\sqrt{2}}})^4 - 4\)
= \(2(\frac{3}{\sqrt{2}})^2 - 4\)
= \(2(\frac{9}{2}) - 4\)
= 9 - 4
= 5
অতএব, fog(5) = 5 🥳
