A. (4) और (5)(4) and (5)
क्योंकि (16<18<25), इसलिए \(4<\sqrt{18}<5\)। परीक्षा में वर्गों की तुलना पहले करें। / Since (16<18<25), we get \(4<\sqrt{18}<5\). In exams, compare perfect squares first.

If (2.357) is to be shown between (2.35) and (2.36) on the number line, to which value is it closer?
B. (2.36)
(2.357) की (2.36) से दूरी (0.003) और (2.35) से दूरी (0.007) है। छोटी दूरी वाला बिंदु अधिक निकट होता है। / The distance from (2.357) to (2.36) is (0.003), and to (2.35) is (0.007). The smaller distance gives the closer point.

Between which two consecutive integers is \( -\sqrt{7} \) located on the number line?
A. ( -3) और (-2)( -3) and (-2)
क्योंकि \(2<\sqrt{7}<3\), इसलिए \(-3<-\sqrt{7}<-2\)। ऋणात्मक संख्या में क्रम उलटने पर ध्यान रखें। / Since \(2<\sqrt{7}<3\), we have \(-3<-\sqrt{7}<-2\). For negative numbers, remember the order reverses.

At which decimal point will \( \frac{17}{5} \) be marked on the number line?
B. (3.4)
\( \frac{17}{5}=3.4 \), इसलिए बिंदु (3) और (4) के बीच होगा। भिन्न को दशमलव में बदलकर स्थान तय करें। / \( \frac{17}{5}=3.4 \), so the point lies between (3) and (4). Convert the fraction to a decimal to locate it.

A. \(1+\sqrt{6}\)
दाईं ओर जाने पर संख्या जोड़ी जाती है, इसलिए निर्देशांक \(1+\sqrt{6}\) होगा। दिशा देखकर चिह्न चुनें। / Moving right means addition, so the coordinate is \(1+\sqrt{6}\). Choose the sign by checking the direction.

Which option correctly describes \( \frac{-13}{4} \) on the number line?
A. यह (-4) और (-3) के बीच हैIt lies between (-4) and (-3)
\( \frac{-13}{4}=-3.25\), जो (-4) और (-3) के बीच आता है। ऋणात्मक दशमलव को बाईं ओर रखें। / \( \frac{-13}{4}=-3.25\), which lies between (-4) and (-3). Place negative decimals to the left side.

A. (a,b,c)
क्योंकि (2<3<5), इसलिए \( \sqrt{2}<\sqrt{3}<\sqrt{5}\)। धनात्मक वर्गमूल में अंदर की संख्या से क्रम तय होता है। / Since (2<3<5), \( \sqrt{2}<\sqrt{3}<\sqrt{5}\). For positive square roots, order follows the radicand.

Which is the best estimate for showing \( \sqrt{45} \) on the number line?
A. (6.7)
क्योंकि \(6^2=36\) और \(7^2=49\), इसलिए \( \sqrt{45}\) लगभग (6.7) है। निकटतम पूर्ण वर्गों से अनुमान लगाएँ। / Since \(6^2=36\) and \(7^2=49\), \( \sqrt{45}\) is about (6.7). Estimate using nearby perfect squares.

Among ( -1.08 ), ( -1.8 ), ( -1.18 ), and ( -1.01 ), which will be farthest left on the number line?
A. ( -1.8)
सबसे छोटी संख्या संख्या रेखा पर सबसे बाईं ओर होती है, और (-1.8) सबसे छोटी है। ऋणात्मक दशमलव में अधिक परिमाण का मतलब अधिक बायाँ होता है। / The smallest number is farthest left, and (-1.8) is the smallest. For negative decimals, larger magnitude means farther left.

Between which two integers will \( \sqrt{12}-1 \) lie on the number line?
A. (2) और (3)(2) and (3)
\(3<\sqrt{12}<4\), इसलिए \(2<\sqrt{12}-1<3\)। पहले मूल का अंतराल निकालें, फिर घटाएँ। / Since \(3<\sqrt{12}<4\), \(2<\sqrt{12}-1<3\). First find the root interval, then subtract.
