Correct Answer: $5$

Solution : $N=\frac{(\sqrt7-\sqrt3)}{(\sqrt7+\sqrt3)}$, then what is the value of $N+(\frac{1}{N})$
$\frac{1}{N}=\frac{(\sqrt7+\sqrt3)}{(\sqrt7-\sqrt3)}$
To find: $N+(\frac{1}{N})$
Putting the values, we get:
$\frac{(\sqrt7-\sqrt3)}{(\sqrt7+\sqrt3)}+\frac{(\sqrt7+\sqrt3)}{(\sqrt7-\sqrt3)}$
= $\frac{(\sqrt7-\sqrt3)^2+(\sqrt7+\sqrt3)^2}{(\sqrt7+\sqrt3)(\sqrt7-\sqrt3)}$
= $\frac{(7+3-2\sqrt7\sqrt3)+(7+3+2\sqrt7\sqrt3)}{(7-3)}$
= $\frac{20}{4}$
= 5
Hence, the correct answer is $5$.

Correct Answer: $60$

Solution : Given: The expression is $9\times [(9 - 4) \div {\{(8 \div 8\ \text{of}\ 4) +(4 \div 4 \ \text{of}\ 2)}\}]$
$=9\times [(9 - 4) \div {\{(8 \div 32) +(4 \div 8)}\}]$
$=9\times [5 \div (\frac{1}{4} +\frac{1}{2})]$
$=9\times [5 \div \frac{3}{4}]$
$=9\times [5\times \frac{4}{3}]=9\times \frac{20}{3}=60$
Hence,

Correct Answer: 1 cm

Solution : Let $a$ and $b$ be the two sides other than the hypotenuse.
Use the Pythagoras theorem: Hypotenuse² = Base² + Perpendicular²
According to the question,
 $(29)^{2} = a^{2} + b^{2}$
⇒ 841 = $a^{2} + b^{2}$
Also, $a +  b$ =
