What is the main difference between (a+b) and (ab)?
A. (a+b) योग है और (ab) गुणन है(a+b) is sum and (ab) is product
चिह्न (+) योग दिखाता है और साथ लिखना गुणन दिखाता है। इसलिए (a+b) और (ab) अलग व्यंजक हैं। / The sign (+) shows addition and writing together shows multiplication. So (a+b) and (ab) are different expressions.

Which expression represents adding (3) to the square of (x)?
A. \(x^2+3\)
(x) का वर्ग \(x^2\) है और उसमें (3) जोड़ने पर \(x^2+3\) मिलता है। शब्दों में क्रम समझना जरूरी है। / The square of (x) is \(x^2\), and adding (3) gives \(x^2+3\). Understanding the order of words is important.

What is the simplified form of (2x+3x+4x)?
A. (9x)
समान पदों के गुणांक (2+3+4=9) हैं। इसलिए सरल रूप (9x) है। / The coefficients of like terms are (2+3+4=9). Therefore the simplified form is (9x).

What is the simplified form of (x+0)?
B. (x)
किसी व्यंजक में (0) जोड़ने से उसका मान नहीं बदलता। इसलिए (x+0=x)। / Adding (0) to an expression does not change its value. So (x+0=x).

What is the simplified form of \(1\cdot x\)?
C. (x)
किसी चर को (1) से गुणा करने पर वही चर मिलता है। इसलिए \(1\cdot x=x\)। / Multiplying a variable by (1) gives the same variable. Therefore \(1\cdot x=x\).

What is the simplified form of \(0\cdot y+6\)?
D. (6)
\(0\cdot y=0\), इसलिए \(0\cdot y+6=6\)। शून्य से गुणा हमेशा (0) देता है। / \(0\cdot y=0\), so \(0\cdot y+6=6\). Multiplication by zero always gives (0).
