यदि (x=-9) है तो \( \sqrt{x^2}+3x \) का मान क्या होगा?
If (x=-9), what is the value of \( \sqrt{x^2}+3x \)?
Explanation opens after your attempt
A. ( -18 )
Concept
\( \sqrt{x^2}=|x|=9 \) and (3x=-27). Therefore the total is (9-27=-18).
Why this answer is correct
The correct answer is A. ( -18 ). \( \sqrt{x^2}=|x|=9 \) and (3x=-27). Therefore the total is (9-27=-18).
Exam Tip
\( \sqrt{x^2}=|x|=9 \) और (3x=-27) है। इसलिए कुल (9-27=-18) मिलेगा।
