यदि ((r+12)x^{12}+(r+12)x-5+26) की डिग्री (0) है, तो (r) का मान क्या है?
If the degree of ((r+12)x^{12}+(r+12)x-5+26) is (0), what is the value of (r)?
Explanation opens after your attempt
B. (r=-12)
Concept
For degree (0), both variable terms must vanish. From (r+12=0), we get (r=-12).
Why this answer is correct
The correct answer is B. (r=-12). For degree (0), both variable terms must vanish. From (r+12=0), we get (r=-12).
Exam Tip
डिग्री (0) के लिए दोनों चर पद हटने चाहिए। (r+12=0) से (r=-12) मिलता है।
