If $p = 99$,then the value of $p(p^{2} + 3p + 3)$ is:

If $a = \sqrt{2} + 1$ and $b = \sqrt{2} - 1,$ then the value of $\frac{1}{a + 1} + \frac{1}{b + 1}$ will be

$A$ pineapple costs $Rs. 7$ each. $A$ watermelon costs $Rs. 5$ each. $X$ spends $Rs. 38$ on these fruits. The number of watermelons purchased is

$138.009 + 341.981 - 146.305 = 123.6 + ?$

$3.75 + 2.832 - 1.001 + 1.803 = ?$

The value of $\frac{1.073 \times 1.073 - 0.927 \times 0.927}{1.073 - 0.927} + \frac{(3^4)^4 \times 9^6}{(27)^7 \times 3^9}$ is
