यदि \(x^{2}=3\), तो \(x^{6}-x^{4}\) का मान क्या है?
If \(x^{2}=3\), what is the value of \(x^{6}-x^{4}\)?
Explanation opens after your attempt
Correct Answer
A. (18)
Concept
Here (x^{6}=\(x^{2}\)^{3}=27) and (x^{4}=\(x^{2}\)^{2}=9), so the difference is (18). In exams, express powers using the given \(x^{2}\).
Why this answer is correct
The correct answer is A. (18). Here (x^{6}=\(x^{2}\)^{3}=27) and (x^{4}=\(x^{2}\)^{2}=9), so the difference is (18). In exams, express powers using the given \(x^{2}\).
Exam Tip
(x^{6}=\(x^{2}\)^{3}=27) और (x^{4}=\(x^{2}\)^{2}=9), इसलिए अंतर (18) है। परीक्षा में दी हुई घात \(x^{2}\) के रूप में लिखें।
