यदि ((r-2)x-7+(r-2)x-3+8) की डिग्री (0) है, तो (r) का मान क्या है?
If the degree of ((r-2)x-7+(r-2)x-3+8) is (0), what is the value of (r)?
Explanation opens after your attempt
A. (r=2)
Concept
For degree (0), both variable terms must vanish. From (r-2=0), we get (r=2).
Why this answer is correct
The correct answer is A. (r=2). For degree (0), both variable terms must vanish. From (r-2=0), we get (r=2).
Exam Tip
डिग्री (0) के लिए दोनों चर पद हटने चाहिए। (r-2=0) से (r=2) मिलता है।
