Here \(\alpha+\beta=-1\) and \(\alpha\beta=-1\). The power sums give \(S_1=-1\), \(S_2=3\), \(S_3=-4\), \(S_4=7\), \(S_5=-11\).
Step 2
Why this answer is correct
The correct answer is A. (-11). Here \(\alpha+\beta=-1\) and \(\alpha\beta=-1\). The power sums give \(S_1=-1\), \(S_2=3\), \(S_3=-4\), \(S_4=7\), \(S_5=-11\).
Step 3
Exam Tip
यहाँ \(\alpha+\beta=-1\) और \(\alpha\beta=-1\) है। शक्ति योग क्रम से \(S_1=-1\), \(S_2=3\), \(S_3=-4\), \(S_4=7\), \(S_5=-11\) मिलता है।
Here \(\alpha+\beta=8\) and \(\alpha\beta=15\). The value is (\frac{\(\alpha+\beta\)2-2\alpha\beta}{\alpha\beta}=\frac{34}{15}).
Step 2
Why this answer is correct
The correct answer is A. \(\frac{34}{15}\). Here \(\alpha+\beta=8\) and \(\alpha\beta=15\). The value is (\frac{\(\alpha+\beta\)2-2\alpha\beta}{\alpha\beta}=\frac{34}{15}).
Step 3
Exam Tip
यहां \(\alpha+\beta=8\) और \(\alpha\beta=15\) है। मान (\frac{\(\alpha+\beta\)2-2\alpha\beta}{\alpha\beta}=\frac{34}{15}) होगा।
Here \(\alpha+\beta=7\) and \(\alpha\beta=12\). (\frac{\alpha}{\beta}+\frac{\beta}{\alpha}=\frac{\(\alpha+\beta\)2-2\alpha\beta}{\alpha\beta}=\frac{25}{12}).
Step 2
Why this answer is correct
The correct answer is A. \(\frac{25}{12}\). Here \(\alpha+\beta=7\) and \(\alpha\beta=12\). (\frac{\alpha}{\beta}+\frac{\beta}{\alpha}=\frac{\(\alpha+\beta\)2-2\alpha\beta}{\alpha\beta}=\frac{25}{12}).
Step 3
Exam Tip
यहां \(\alpha+\beta=7\) और \(\alpha\beta=12\) है। (\frac{\alpha}{\beta}+\frac{\beta}{\alpha}=\frac{\(\alpha+\beta\)2-2\alpha\beta}{\alpha\beta}=\frac{25}{12}) होगा।
