यदि ((r-8)x-9+(r-8)x-2+14) की डिग्री (0) है, तो (r) का मान क्या है?
If the degree of ((r-8)x-9+(r-8)x-2+14) is (0), what is the value of (r)?
Explanation opens after your attempt
A. (r=8)
Concept
For degree (0), both variable terms must vanish. From (r-8=0), we get (r=8).
Why this answer is correct
The correct answer is A. (r=8). For degree (0), both variable terms must vanish. From (r-8=0), we get (r=8).
Exam Tip
डिग्री (0) के लिए दोनों चर पद हटने चाहिए। (r-8=0) से (r=8) मिलता है।
