Which option correctly gives the two nearest integers between which \(\sqrt{7}\) lies?
A. (2) और (3)(2) and (3)
क्योंकि (4<7<9) इसलिए \(2<\sqrt{7}<3\)। जड़ की स्थिति वर्गों से पहचानें। / Since (4<7<9), \(2<\sqrt{7}<3\). Locate roots using squares.

Which option correctly compares \(\sqrt{90}\) and \(\sqrt{99}\)?
A. \(\sqrt{99}>\sqrt{90}\)
धनात्मक संख्याओं में अंदर की संख्या बड़ी हो तो वर्गमूल भी बड़ा होता है। (99>90) है। / For positive numbers a larger number inside the square root gives a larger value. Here (99>90).

Which option is the simplified form of \(\frac{3}{\sqrt{3}}\)?
A. \(\sqrt{3}\)
\(\frac{3}{\sqrt{3}}=\sqrt{3}\) क्योंकि \(3=\sqrt{3}\times\sqrt{3}\)। हर में जड़ हो तो सरल करें। / \(\frac{3}{\sqrt{3}}=\sqrt{3}\) because \(3=\sqrt{3}\times\sqrt{3}\). Simplify when a root is in the denominator.
