What is the value of \(2+3^2\cdot2\)?
A. (20)
पहले \(3^2=9\), फिर \(9\cdot2=18\), और (2+18=20)। घात का काम गुणा से पहले करें। / First \(3^2=9\), then \(9\cdot2=18\), and (2+18=20). Exponents are evaluated before multiplication.

What is the simplified form of \(4x^2+3x^2\)?
A. \(7x^2\)
ये समान पद हैं इसलिए गुणांक (4+3=7) जोड़े जाते हैं। घात (2) वही रहती है। / These are like terms, so the coefficients (4+3=7) are added. The exponent (2) remains the same.

What is the simplified form of \(6x^3-2x^3\)?
A. \(4x^3\)
समान पदों में गुणांक घटते हैं इसलिए \(6x^3-2x^3=4x^3\)। चर और घात नहीं घटते। / For like terms, coefficients are subtracted, so \(6x^3-2x^3=4x^3\). Variables and exponents are not subtracted.

How many terms are there in (2x+3y)?
B. (2)
(2x+3y) में (2x) और (3y) दो पद हैं। पदों को जोड़ या घटाव के चिह्न से अलग पहचानें। / In (2x+3y), the two terms are (2x) and (3y). Identify terms by plus or minus signs.

Which of the following is a like term of \(x^2\)?
A. \(3x^2\)
समान पद में चर और घात समान होते हैं। \(3x^2\) में \(x^2\) वही है इसलिए यह समान पद है। / Like terms have the same variable and exponent. In \(3x^2\), \(x^2\) is the same, so it is a like term.

What is the product of \(3x^2\cdot2x\)?
C. \(6x^3\)
गुणांक \(3\cdot2=6\) और \(x^2\cdot x=x^3\) है। इसलिए गुणनफल \(6x^3\) है। / The coefficients give \(3\cdot2=6\), and \(x^2\cdot x=x^3\). So the product is \(6x^3\).

What is the simplified form of \(18a^5\div6a^2\) if \(a\neq0\)?
A. \(3a^3\)
\(\frac{18}{6}=3\) और \(\frac{a^5}{a^2}=a^3\) है। इसलिए उत्तर \(3a^3\) है। / \(\frac{18}{6}=3\) and \(\frac{a^5}{a^2}=a^3\). Therefore the answer is \(3a^3\).

What is the simplified form of \(2^3\cdot2^0\cdot2^2\)?
A. \(2^5\)
समान आधार में घातें (3+0+2=5) जुड़ती हैं। इसलिए सरल रूप \(2^5\) है। / For the same base, the exponents add as (3+0+2=5). Hence the simplified form is \(2^5\).

What is the simplified form of (\(5^2\cdot5^3\)\div54)?
A. \(5^1\)
समान आधार में पहले घातें (2+3=5) जुड़ती हैं और फिर (5-4=1) बचता है। इसलिए सरल रूप \(5^1\) है। / For the same base, first add exponents (2+3=5), then subtract (5-4=1). So the simplified form is \(5^1\).

What is the value of (\left\(\frac{2}{3}\right\)0+\left\(\frac{1}{2}\right\)2)?
C. \(\frac{5}{4}\)
(\left\(\frac{2}{3}\right\)0=1) और (\left\(\frac{1}{2}\right\)2=\frac{1}{4}) है। इसलिए योग \(\frac{5}{4}\) है। / Here (\left\(\frac{2}{3}\right\)0=1) and (\left\(\frac{1}{2}\right\)2=\frac{1}{4}). Therefore the sum is \(\frac{5}{4}\).
